WAP_E01: Write a C program that uses functions to insert a sub-string into a given main string from a given position|| Strings
WAP_E01: C Lab Program
//insert a sub-string into a given main string from a given position.
#include <stdio.h>
#include <string.h>
int main() {
char mainStr[50], subStr[50],finalStr[100];
int position;
// Input the main string
printf("Enter the main string: ");
fgets(mainStr, sizeof(mainStr), stdin);
// Input the substring
printf("Enter the substring: ");
fgets(subStr, sizeof(subStr), stdin);
subStr[strcspn(subStr, "\n")] = '\0'; // Remove newline
// Input the position
printf("Enter the position to insert the substring: ");
scanf("%d", &position);
// Check if the position is valid
int mainLen = strlen(mainStr);
if (position < 0 || position > mainLen) {
printf("Invalid position.\n");
return 1;
}
strncpy(finalStr,mainStr,position); // Copy string up to position
strcat(finalStr,subStr); // Insert substring
strcat(finalStr,mainStr+position); // Append remaining part
// Print the result string
printf("Modified string: %s\n", finalStr);
return 0;
