Return Type : char *

String pointer (array of characters)

Read about return values of strcat function .

1st Parameter Type : char *

String pointer (array of characters)

1st Parameter

Pointer to the destination null-terminated string where the content of `src` will be appended.

2nd Parameter Type : const char *

Pointer to read-only string

2nd Parameter

Pointer to the source null-terminated string to append to `dest`.

The strcatfunction in C language Appends the source string to the destination string.

The strcat function appends a copy of the source string to the destination string. The terminating null character in destination is overwritten by the first character of source, and a new null-character is appended at the end of the new string formed by the concatenation of both in destination.

The strcatfunction takes 2 parameters:

•
char * `dest`: Pointer to the destination null-terminated string where the content of `src` will be appended.
•
const char * `src`: Pointer to the source null-terminated string to append to `dest`.

Appends the source string `src` to the destination string `dest`, overwriting the null terminator at the end of `dest` and adding a new null terminator. The destination string must have enough space to hold the resulting string. Returns a pointer to the destination string `dest`.

The strcat function return value :

Returns a pointer to the resulting string destination

Output

This example demonstrates basic usage of strcat to concatenate two strings.
