c - loop 2 taking input automatically

Question

My code is behaving weirdly. In loop 1 it is working perfectly but in loop 2 it is automatically printing ASCII value 10. please help!.

#include<stdio.h>

int main(){
    char c;
    int loop =1;

    do{

        printf("
Loop = %d
Write character of which you want to find acii values: ", loop);
        scanf("%c", &c);
        printf("
ASCII value of %c is %d.", c, c);
        loop++;

    }while(c != 'Z');

    printf("
******END*****");
    
    return 0;

}

Answer 1

10 is ASCII for newline. You are reading whitespace, which you can avoid by using

scanf(" %c", &c);

Note the additional blank before the character specifier. It instructs scanf to ignore white space.
