Discussion Forum : Declarations and Initializations - Find Output of Program (Q.No. 11)

In the following program how long will the for loop get executed?
#include<stdio.h>
int main()
{
int i=5;
for(;scanf("%s", &i); printf("%d\n", i));
return 0;
}
Answer: Option
Explanation:
During the for loop execution scanf() ask input and then printf() prints that given input. This process will be continued repeatedly because, scanf() returns the number of input given, the condition is always true(user gives a input means it reurns '1').
Hence this for loop would get executed infinite times.

The 'for-loop' declaration is wrong so it will not execute.

If we enter 0 then also it should go into infinite loop.
