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 ", 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 _________.

1. In main(), x = "abc" has length $3$, and y = "defgh" has length $5$.

2. In printlength(s, t):

   • strlen(s) returns (size_t) 3

   • strlen(t) returns (size_t) 5

3. The subtraction strlen(s) - strlen(t) is performed using unsigned arithmetic:

   $$3\text{U} - 5\text{U} = \text{UINT\_MAX} - 1$$

   which results in a very large positive unsigned integer (e.g., $4294967294$ on a 32-bit system).

4. The comparison (strlen(s) - strlen(t)) > c compares this large unsigned value with c = 0U, which evaluates to true ($1$).

5. Since the condition is true, the ternary operator selects strlen(s), which is $3$.

6. Therefore, len = 3, and `printf("%d

", len)` prints 3.
