Write a program to concatenate two string in c

C program to concatenate two strings

Concatenating two strings means joining them together to form a single string. In C, string concatenation is performed using the strcat function, which is available in the standard C library.

Introduction

This program demonstrates how to concatenate two strings in C. Concatenation is the process of joining two strings together to form a new string. This is a common operation in C programming, and it is used in many different applications, such as text processing, data manipulation, and web development.

How to use the strcat() function to concatenate two strings:

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

int main() {
  char str1[100], str2[100], concatenatedStr[200];

  printf("Enter the first string: ");
  scanf("%s", str1);

  printf("Enter the second string: ");
  scanf("%s", str2);

  // Concatenate the two strings into the concatenatedStr variable
  strcat(concatenatedStr, str1);
  strcat(concatenatedStr, str2);

  // Print the concatenated string
  printf("The concatenated string is: %s\n", concatenatedStr);

  return 0;
}

Output

Enter the first string: Hello
Enter the second string: World
The concatenated string is: HelloWorld

Conclusion

This program demonstrates how to concatenate two strings in C. The strcat() function is a simple and efficient way to join two strings together to form a new string.
