To understand this example, you should have the knowledge of the following C programming topics:
·
Relationship Between Arrays and Pointers
·
C Pass Addresses and Pointers
As you know, the best way to copy a string is by using the strcpy()
function. However, in this example, we will
copy a string manually without using the strcpy()
function.
Copy String Without Using strcpy()
#include <stdio.h>
int main() {
char s1[100], s2[100], i;
printf("Enter string s1: ");
fgets(s1, sizeof(s1), stdin);
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: Hey fellow programmer.
String s2: Hey fellow programmer.
The above program copies the content of string s1 to string s2 manually.
