C program to print all odd numbers between 1 and 100








#include<stdio.h>
int main(){
    int i;
    for(i=1;i<100;i=i+2){
    printf("%d\n",i);

i dont understand the solutions pliiz help.....what does "%d"/n",i mean?

Ritesh kumar said...

prinf function is formated function.
"%d\n" is format. Here
%d represent decimal number or integer type number
\n is new line character.

We have used %d since variable is integer type variable and in the output %d will be replaced by value i.

If you have still doubt the you are welcome.

where use i value

what does i=i+2

what does i+2?

since the program is to find odd numbers from 1 to 100 , we use for loop. Here i=2 is the initialization,i<100 is the condition and i=i+2 is the increment operation i.e it will increment the condition. Here i=i+2 is to find for odd numbers.So all the numbers b/w 1 and 100 will get printed .

sorry odd numbers will get printed.

Initially i value is 1 so loop add 1+2 = 3

sir if user prints two unknown number and we have to find all the odd numbers between them then what should we do????

/*Find the even no and their sum*/
#include
main()
{
int i=1,n,s=0;
printf("enter the value of n\n");
scanf("%d",&n);
while(i<=n)
{
if(i%2==0)
{
printf(" %d ",i);
s=s+i;
}
i++;
}
printf("\n");
printf("s=%d\n",s);
}

if you want to take input i also user than not declare i=0, also take value of i from user same taken from n,but carefully at user input end I is less than N.

Well explained

APURBA said...

in line number 14 you have stated if (i%2==0), what does it mean?

unknown said...

It means if d value of i is divided by 2 and if d remainder is equal to 0 den the value of i is an even number!! for eg. assume that if i=2 den from d if condition it is divisible by 2 n d remainder is 0 so the value of i wud b printd as an even number

why the program is coming when the void is placed in it ????????

one more way of doing is

#include


int main()
{
int i;
int a;
for(i=0;i<50;i++)
{
a=(2*i)+1;
printf("%d",a);
}
}
