The strcat(first_str, second_str) function concatenates the two strings and the result is returned to first_str.
In the C programming language, the strcat( ) function appends a copy of the string pointed to by second_str2 to the end of the string pointed to by first_str1. It returns a pointer to srt1 where the resulting concatenated string resides.
* Syntax:
char *strcat(char *str1, const char *str2);* Parameters or Arguments :
str1 - A pointer to a string that will be modified. str2 will be copied to the end of str1.
str2 - A pointer to a string that will be appended to the end of str1.
src - This is the string to be appended. It should not overlap the destination.
* Returns:
strcat फ़ंक्शन str1 पर एक पॉइंटर लौटाता है ( जहां परिणामी संयोजित स्ट्रिंग रहती है )।
* Required Header :
In the C language, the required header for the strcat( ) function is:
#include <string.h>* Pay Attention :
Use the strcat() function with care, because it's easy to add more bytes to your variable using the strcat() function, which can lead to unexpected behavior.
* It Applies :
In the C language, the strcat() function can be used in the following versions:
ANSI/ISO 9899-1990
