Why is the output here "Sololearn"?

Question

#include <stdio.h>

int main() {
int i=0;
switch(i){
case '0': printf("Solo");
break;
case '1':printf("Learn");
break;
default:printf("Sololearn");
}
return 0;
}

Answer 1

There is no switch option for integer 0 so default switch is used.

Answer 2

maybe you didn't notice quotes))
0 is not equal to '0' and is not equal to '1'

Answer 3

0 and 1 are characters inside switch. When you compare an integer with character, ASCII value of the character is matched with the character. And ASCII value of character 0 is not equal to 0.
