//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; }
