Consider the following C program.
#include<stdio.h>
#include<string.h>
void printlength(char *s, char *t) {
unsigned int c=0;
int len = ((strlen(s) - strlen(t)) > c) ? strlen(s) : strlen(t);
printf("%d\n", len);
}
void main() {
char *x = "abc";
char *y = "defgh";
printlength(x,y);
}
Recall that $strlen$ is defined in $string.h$ as returning a value of type $size\_t$, which is an unsigned int. The output of the program is __________ .
