How to Append a String to another String in C - Step by Step Examples

How to Append a String to another String in C ?

To append a string to another string in C, you can use the strcat function.

In this example,

We create an array of characters named str1 initialized with "Hello".
We then use the strcat function to append the string " World" to str1.
The strcat function concatenates the two strings and modifies the original str1.
Finally, we print the concatenated string to the console.

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

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

Hello World

In this example,

We create an array of characters named str2 initialized with "banana".
We then use the strcat function to append the string "apple" to str2.
The strcat function concatenates the two strings and modifies the original str2.
Finally, we print the concatenated string to the console.

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

int main() {
    char str2[20] = "banana";
    strcat(str2, "apple");
    printf("%s", str2);
    return 0;
}
