Can you give me some examples of string manipulation in C?

Sure! Here are a few common string manipulation functions in C: strcpy, strcat, strlen, and strcmp.

Can you explain how to use strcat?

Of course! The strcat function appends one string to another. For example, if you have two strings, str1 and str2, you can use strcat(str1, str2) to append str2 to str1.

What about finding the length of a string?

You can use the strlen function to find the length of a string. For example, strlen(str) will return the number of characters in str, excluding the null terminator.

Can you show me a complete example?

Certainly! Here's a simple example:

#include <stdio.h>
#include <string.h>

int main() {
    char str1[20] = "Hello";
    char str2[20] = " World!";
    strcat(str1, str2);
    printf("%s\n", str1);
    return 0;
}

This will output "Hello World!".
