Life, the Universe, and Everything: time exceeded

m getting time limit exceeded for the following code:

#include<stdio.h>

int main()
{
     int num;
     while(scanf("%d",&num)!=42)
         printf("%d\n",num);
     return 0;
}

scanf doesnt return the number you input.

this is your corrected code…

#include<stdio.h>
int main()
{
    int num;
    scanf("%d",&num);
    while(num!=42)
    {
        printf("%d\n",num);
        scanf("%d",&num);
    }
    return 0;
}

scanf returns the number of fresh inputs it has taken…like if u take 1 i/p it returns 1…eg…

scanf("%d",n);

this will store the i/p in n and return 1

similarly…

scanf("%d %d",&n,&n1);

this will store the respective ips and return 2…as the number of inputs taken are 2…

if u call the fxn and it encounters EOF(end of file) then it will return -1…with the previous number as it was in that var…you can see this link…LINK…hope this helps…:slight_smile:
