C Program to Copy String Without Using strcpy()

In this article, you'll learn to copy string without using the library function strcpy().

To understand this example, you should have the knowledge of following C programming topics:

You can use the strcpy() function to copy the content of one string to another but, this program copies the content of one string to another manually without using strcpy() function.

Example: Copy String Manually Without Using strcpy()

#include <stdio.h>
int main()
{
    char s1[100], s2[100], i;

    printf("Enter string s1: ");
    scanf("%s",s1);

    for(i = 0; s1[i] != '\0'; ++i)
    {
        s2[i] = s1[i];
    }

    s2[i] = '\0';
    printf("String s2: %s", s2);

    return 0;
}

Output

Enter String s1: programiz 
String s2: programiz

This above program copies the content of string s1 to string s2 manually.
