This is the simple implementation of the “Copy” function of the computer world. This program copies the content of one string to another.
Logic : The program asks the user to input the string to copy and stores this as str1. The inner function “stcpy” takes 2 strings as arguments. By keeping the length as the reference, it traces till EOL , for each i of this iteration, it copies the i-th letter to the destination string, i.e str2.
After the EOL, it puts a NULL to the second line. That gives the duplicated string of the entered.
void stcpy(char str1, char str2);
char str1, str2;
printf(“\n\n\t ENTER A STRING…: “);
printf(“\n\t THE COPIED STRING IS…: “);
void stcpy(char str1, char str2)
int i, len = 0;
str2[i] = str1[i];
str2[i] = ‘\0′;
