What is the output of the below program?
#include <stdio.h>
int main()
{
int i = 0;
switch (i)
{
case '0': printf("Geeks");
break;
case '1': printf("Quiz");
break;
default: printf("GeeksQuiz");
}
return 0;
}
Answer: C
Correct answer: GeeksQuiz
'0' is a character constant, and its value is the ASCII code 48, not the number 0. Likewise '1' is 49. The controlling expression is 0, which matches neither, so control falls to default.
