C Program to Copy a Source String to a Destination String

Copy the source string into the destination string" means to make a copy of the characters in the source string and store them in the destination string so that the contents of the destination string are identical to the contents of the source string.

Write a c program to copy the source string into the destination string using for loop

#include
void main()
{
    int s[10],d[10];
    int i;
    printf("Enter the string:");
    scanf("%s",s);
    printf("Entered string is:%s\n",s);
    for(i=0;s[i];i++)
    d[i]=s[i];
    printf("s=%s  d=%s\n",s,d);

}

Output

Enter the string: ELECTRO4u
Entered string is : ELECTRO4u
s=ELECTRO4u  d=ELECTRO4u

C program to delete some characters in a given string:

#include <stdio.h>
#include <string.h>

void delete_characters(char *str, int start, int end) {
  int i;

  for (i = start; i <= end; i++) {
    str[i] = str[i + 1];
  }

  str[end] = '\0';
}

int main() {
  char str[100];
  int start, end;

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

  printf("Enter the start and end positions of the characters to delete: ");
  scanf("%d %d", &start, &end);

  delete_characters(str, start, end);

  printf("The string after deleting the characters is: %s\n", str);

  return 0;
}

This program works by first prompting the user to enter a string and the start and end positions of the characters to delete. It then uses the delete_characters() function to delete the specified characters from the string. The delete_characters() function works by shifting the remaining characters in the string to the left to fill in the gaps left by the deleted characters.

Output

Enter a string: Hello, world!
Enter the start and end positions of the characters to delete: 7 11
The string after deleting the characters is: Hello, !
