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);

big=a;
if(big<b) big=b;
if(big<c) big=c;
printf("%d",big);

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


#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();
}

Ritesh kumar said...

I think you have missed the & in scanf statement.
Replace scanf(" %d",a[i][j]); by
scanf(" %d",&a[i][j]);

I hope this will help you.

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

T-50 said...

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....

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..

Tapas kumar pal said...

cout<<"Enter the values";
cin>>a>>b>>c;
if(a>b)
{
if(a>c)
{
m=a;
}
else
{
m=c;
}
}
else
{
if(b>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


#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;
}

thanks

not bad bro..

Anonymous said...

while reading the elements u have not used & in scanf,so the elements are getting stored, correct it as:
scanf(" %d",&a[i][j]);

Nikhil said...

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



static int max(int arr[])
{
int i;
for(i=0;iarr[i+1])
{
int temp=arr[i];
arr[i]=arr[i+1];
arr[i+1]=temp;
}
}
int mx=arr[i];
return mx;
}

pls explain this program

printf("n Enter no of elements :");
scanf("%d",&n);

/* read n elements in an array */
for(i=0 ; i < n ; i++)
scanf("%d",&a[i]);

largest = a[0];

for(i = 0;i largest )
largest = a[i];
}

/* Print out the Result */
printf("nLargest Element : %d",largest);
getch();
}

jagadeesh pulamarasetti said...

#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

thats it...
