Add source string at the end of destination string in c
Concatenating Strings in C: Adding Source to Destination
To add a source string at the end of a destination string in C, you can use the following steps:
- Declare a pointer to the destination string.
- Declare a pointer to the source string.
- Find the end of the destination string by iterating through it until you reach the null character
(\0). - Copy the source string to the end of the destination string, starting at the position you found in step 3.
- Add a null character to the end of the destination string.
Example of a C function that adds a source string at the end of a destination string:
C Programming
#include <string.h>
char *add_source_string_at_the_end_of_destination_string(char *destination_string, char *source_string) {
// Find the end of the destination string.
char *destination_string_end = destination_string;
while (*destination_string_end != '\0') {
destination_string_end++;
}
// Copy the source string to the end of the destination string.
while (*source_string != '\0') {
*destination_string_end = *source_string;
destination_string_end++;
source_string++;
}
// Add a null character to the end of the destination string.
*destination_string_end = '\0';
// Return the destination string.
return destination_string;
}To use the add_source_string_at_the_end_of_destination_string() function, you would simply pass in the destination string and the source string as arguments. The function would then return a pointer to the destination string with the source string appended to the end.
Example of how to use the add_source_string_at_the_end_of_destination_string() function:
C Programming
#include <stdio.h>
#include <string.h>
int main() {
char destination_string[] = "This is a test string.";
char source_string[] = " This is a source string.";
// Add the source string to the end of the destination string.
char *new_string = add_source_string_at_the_end_of_destination_string(destination_string, source_string);
// Print the new string.
printf("%s\n", new_string);
return 0;
}Output:
This is a test string. This is a source string.Further Reading:
