Question

Q5. Implement a C program that includes a function that copies one string into another string. You cannot use string.h library for this exercise. Use the following function prototype: void copystring(chars1 ().char s2[]); A sample run would be as follows: Please enter a string: cngcourse String 1 is copied to String 2 String 1 is cngcourse and String 2 is cngcourse

No pointers please

Urgent!!!

Answer:

 #include <stdio.h> #define MAX_SIZE 100 // Maximum size of the string void copystring(char s1[],char s2[]); int main(int argc, char* argv[]) { char s1[MAX_SIZE]; char s2[MAX_SIZE]; /* Input string from user */ printf("Please enter a string: "); scanf("%[^\n]",s1); copystring(s1,s2); printf("String 1 is copied to String 2 \n"); printf("String 1 is %s and String 2 is %s \n",s1,s2); return 0; } void copystring(char s1[],char s2[]) {          int i;                  /* Copy s1 to s2 character by character */ for(i=0; s1[i]!='\0'; i++) { s2[i] = s1[i]; } //Makes sure that the string is NULL terminated s2[i] = '\0'; }

#include <stdio.h> #define MAX_SIZE 100 // Maximum size of the string void copystring(char s1[], char 52[]); int main(int argc, char* argv[]) { char s1[MAX_SIZE]; char s2[MAX_SIZE]; /* Input string from user */ printf("Please enter a string: "); scanf("%[^\n]", s1); copystring(51, s2); printf("String 1 is copied to String 2 \n"); printf("String 1 is %s and String 2 is %s \n", s1, s2); return 0; } void copystring(char s1[],char 52[]) JO int i; /* Copy si to s2 character by character */ for(i=0; sifil!='\0'; i++)
