Say 1st element is biggest one...... Now big contains 1st element ... Now it compares 2nd element with big and if it is greater it stores dat element else 1st element is biggest... Again 3rd element is compared to big....then 4th....so on....until all are compared then biggest is printed....

please send me simple programming learning tips in c on (cv.welcome.cv@gmail.com). also write me to contact you thorugh my id. i also have some querries regarding programming in c. therefore, i request you to accept my request again.

For second largest element of an array go through the following link: http://cquestionbank.blogspot.com/2008/01/write-c-program-to-find-second-largest.html

# include main() { int i,j,x[200],n; printf ( "\n Enter numbers of element " ); scanf ( "%d",&n ); for ( i=0; i j ) { j=x[i]; } } printf ( "The answer is %d " ,j ); }

#include int main() { int t; scanf("%d",&t); int a[t]; int i=0,j=0,k,l,m=0; for(i=0;ia[i]){ k=a[i]; a[i]=a[j]; a[j]=k; } } } l=a[0]; for(i=0;i<t;i++){ if(l==a[i]){ m++; } } printf("maximum number is %d and it was entered %d times",l,m); }

// print the values between 100 to 200 that are divisible by 7

#include int main(){ int vector[100]={};//all elements are 0 int i=0;//first position of the array int no; int j; for(no=100;no<=200;no++) if(no%7==0){ vector[i]=no;//we start putting the elements in the array, we start at element 0(i=0) i++;//then we move to the next position } printf("The array:\n"); for(j=0;j<=i-1;j++) printf("%d ", vector[j]); printf("\n"); return 0; }

#include int main() { int t; scanf("%d",&t); int a[t]; int i=0,j=0,k,l; for(i=0;ia[i]){ k=a[i]; a[i]=a[j]; a[j]=k; } } } printf("%d",a[1]); }

this is code to get 2nd biggest number... to try my code , follow these rules:- * first enter the number, total numbers you want to enter; * enter all number with gap of space or new line; after you enter all number you will get second largest number...

here is another code to know n th biggest number...

#include int main() { int t; scanf("%d",&t); int a[t]; int i=0,j=0,k,l; for(i=0;ia[i]){ k=a[i]; a[i]=a[j]; a[j]=k; } } } scanf("%d",&l); printf("%d",a[l-1]); }

*enter hoe many numbers you want to enter * enter total numbers * enter n, to know nth biggest number

#include int main(void) { int sum=0,a[4],i,j,max=0; printf("Enter the 10 numbers\n"); for(i=0;i<4;i++){ scanf("%d\n",&a[i]); } printf("The sum of 10 numbers is "); for(i=0;i<4;i++){ sum=sum+a[i];} printf("%d\n",sum);

Dude this is for LARGEST....

ReplyDeleteand NOT for SECOND LARGEST....

give a short code for SECOND LARGEST..

Go through the following link to fiind out second largest element of an array:

ReplyDeletehttp://cquestionbank.blogspot.com/2008/01/write-c-program-to-find-second-largest.html

find the largest number in an array in c which is equals to zero

ReplyDelete#include

ReplyDeleteint main(void) {

int pri, sec, i, v;

int arr[] = {4,10,3,8,6,7,2,7,9,2,0};

pri = sec = 0;

for (i = 0; arr[i]; ++i) {

v = arr[i];

if (v > pri) sec = pri, pri = v;

if (v > sec && v < pri) sec = v;

}

printf("pri is %d, sec is %d\n", pri, sec);

return 0;

}

not bad bro..

Deletewhy u took big=a[0]??? i m nt able to undrstnd please explain......

ReplyDeleteSay 1st element is biggest one......

DeleteNow big contains 1st element ...

Now it compares 2nd element with big and if it is greater it stores dat element else 1st element is biggest...

Again 3rd element is compared to big....then 4th....so on....until all are compared then biggest is printed....

please send me simple programming learning tips in c on (cv.welcome.cv@gmail.com).

ReplyDeletealso write me to contact you thorugh my id. i also have some querries regarding programming in c.

therefore, i request you to accept my request again.

shivee kant singh

thanks.

big=a;

ReplyDeleteif(big<b) big=b;

if(big<c) big=c;

printf("%d",big);

please explain and want o/p..if i tried oly it ll display the biggest no...want to know the second largest no.....how to get the second largest no...

ReplyDeleteplz explain soon

ReplyDeleteFor second largest element of an array go through the following link:

ReplyDeletehttp://cquestionbank.blogspot.com/2008/01/write-c-program-to-find-second-largest.html

# include

ReplyDeletemain()

{

int i,j,x[200],n;

printf ( "\n Enter numbers of element " );

scanf ( "%d",&n );

for ( i=0; i j )

{

j=x[i];

}

}

printf ( "The answer is %d " ,j );

}

HEy can anybody tell me why this program not running . is anything done wrong?

ReplyDelete#include

#include

void main()

{

int a[3][3];

int i,j;

printf("enter the elements of an 3X3 array:\n");

for (i=0;i<3;i++)

{

for (j=0;j<3;j++)

{

scanf(" %d",a[i][j]);

}

}

for (i=0;i<3;i++)

{

printf("\n");

for (j=0;j<3;j++)

{

printf(" %d",a[i][j]);

}

}

getch();

}

I think you have missed the & in scanf statement.

DeleteReplace scanf(" %d",a[i][j]); by

scanf(" %d",&a[i][j]);

I hope this will help you.

while reading the elements u have not used & in scanf,so the elements are getting stored, correct it as:

Deletescanf(" %d",&a[i][j]);

Can you show a code on how to find the largest value in an array and how many times it was entered?. Tnx

ReplyDelete#include

a[i]=a[j];

a[j]=k;

}

}

}

l=a[0];

for(i=0;i<t;i++){

if(l==a[i]){

m++;

}

}

printf("maximum number is %d and it was entered %d times",l,m);

}

some one help me.. to print the values between 100 t0 200 that are divisible by 7.. using for loop to input the value using array concept..

ReplyDeletecout<<"Enter the values";

ReplyDeletecin>>a>>b>>c;

if(a>b)

{

if(a>c)

{

m=a;

}

else

{

m=c;

}

}

{

m=b;

}

else

{

m=c;

}

}

j=0;

for(i=m;i>=2;i--)

{

if(a%i==0 && b%i==0 && c%i==0)

{

j++;

break;

}

}

if(j==0)

cout<<"GCD is 1";

else

cout<<"GCD is"<<i;

getch();

// print the values between 100 to 200 that are divisible by 7

ReplyDelete#include

int main(){

int vector[100]={};//all elements are 0

int i=0;//first position of the array

int no;

int j;

for(no=100;no<=200;no++)

i++;//then we move to the next position

}

printf("The array:\n");

for(j=0;j<=i-1;j++)

printf("%d ", vector[j]);

printf("\n");

return 0;

}

can any1 Write a c program to find the second highest number from a set of numbers.

ReplyDelete#include

Deleteint main()

{

int t;

scanf("%d",&t);

int a[t];

int i=0,j=0,k,l;

for(i=0;ia[i]){

k=a[i];

a[i]=a[j];

a[j]=k;

}

}

}

printf("%d",a[1]);

}

this is code to get 2nd biggest number...

to try my code , follow these rules:-

* first enter the number, total numbers you want to enter;

* enter all number with gap of space or new line;

after you enter all number you will get second largest number...

here is another code to know n th biggest number...

#include

int main()

{

int t;

scanf("%d",&t);

int a[t];

int i=0,j=0,k,l;

for(i=0;ia[i]){

k=a[i];

a[i]=a[j];

a[j]=k;

}

}

}

scanf("%d",&l);

printf("%d",a[l-1]);

}

*enter hoe many numbers you want to enter

* enter total numbers

* enter n, to know nth biggest number

thats it...

Q13 Write a program that adds up two 4x4 arrays and stores the sum in third array.

ReplyDeletecan any one of you solve this programme

DeleteNo i can not solve it.

Deletewe need pleas solve this Q13.

thanks

ReplyDeleteis this right way to find largest element...?

ReplyDeletestatic int max(int arr[])

{

int temp=arr[i];

arr[i]=arr[i+1];

arr[i+1]=temp;

return mx;

}

pls explain this program
