What will be printed?
#include <stdio.h>
void main() {
int x;
scanf("%d", x);
printf("%d", x);
}
a) Prints entered number
b) Garbage value
c) Error
d) Crashes
d) Crashes (missing &x in scanf).
What will be printed?
#include <stdio.h>
void main() {
const int a = 10;
scanf("%d", &a);
printf("%d", a);
}
a) Prints entered number
b) Always prints 10
c) Error
d) Garbage value
c) Error Explanation: a is constant, cannot be modified via scanf.
What will be the output?
#include <stdio.h>
void main()
{
int x = 10;
printf("%d", printf("%d", x));
}
a) 10
b) 102
c) 2
d) Undefined
b) 102
Explanation: Inner printf("%d", x) prints 10 and returns 2 (characters printed). Outer printf prints 2.
printf returns the number of characters successfully printed.
Here, printf("%d", x) prints "10".
