In this article we will learn to implement a C program to copy one string to another. A C program is provided below to copy one string to another without using predefined function strcpy.
Program is as follows:
#include<stdio.h>
#include<string.h>
int main()
{
char str[20];
printf("Enter a string: ");
scanf("%s", str);
char newstr[20];
int i=0;
while(i < strlen(str))
{
newstr[i] = str[i];
i++;
}
newstr[i] = '\0';
printf("Copied string is: %s", newstr);
return 0;
}
Input and output for the above program is as follows:
Enter a string: india
Copied string is: india
