Why This Code Not Executing After enter the value?

#include <stdio.h>
#include <math.h>

int main(){
    int x;
    printf("Enter The Number :");
    scanf(" %d \n" , &x);
    int xS= sqrt(x);
    printf("Square Root of The Given Number : %d" , xS);
}

after entering the value 120 , nothing is happening! I am using Clion. What do I have to Do?

Solution

  • You should remove whitespace and '\n' from the format string of scanf.

    An '\n' or any whitespace character in the format string of scanf consumes an entire sequence of whitespace characters in the input. So the scanf only returns when it encounters the next non-whitespace character, or the end of the input stream.
