plz redo this code in C using system functionsinstead of the standard functions i have: #include #include int main(int argc, char const argv[]) { // if entered file list is not sufficient if (argc < 3) { printf("Enter required file names\n"); exit(0); } // last filename entered would be the resultant file FILE resultFile = fopen(argv[argc - 1], "w"), *f; // checking if file opening is successful or not if (resultFile == NULL) { printf("Error opening file %s\n", argv[argc - 1]); exit(1); } // buffer to read the files line by line char buff[1000]; // loop to read the entered files for (int i = 1; i < argc - 1; ++i) { // opening the file f = fopen(argv[i], "r"); // checking if it opened or not if (f == NULL) { printf("Error opening file %s\n", argv[i]); exit(1); } // reading the file line by line and appending them to the resultFile while (fgets(buff, 1000, f)) { fprintf(resultFile, "%s", buff); } // closing current file fclose(f); } // closing resultFile fclose(resultFile); return 0; }

plz redo this code in C using system functionsinstead of the standard functions i have:

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char const *argv[]) {

        // if entered file list is not sufficient
        if (argc < 3) {
                printf("Enter required file names\n");
                exit(0);
        }

// last filename entered would be the resultant file
FILE *resultFile = fopen(argv[argc - 1], "w"), *f;

        // checking if file opening is successful or not
        if (resultFile == NULL) {
                printf("Error opening file %s\n", argv[argc - 1]);
                exit(1);
        }

// buffer to read the files line by line
char buff[1000];

        // loop to read the entered files
        for (int i = 1; i < argc - 1; ++i) {
                // opening the file
                f = fopen(argv[i], "r");

                // checking if it opened or not
                if (f == NULL) {
                        printf("Error opening file %s\n", argv[i]);
                        exit(1);
                }

                // reading the file line by line and appending them to the resultFile
                while (fgets(buff, 1000, f)) {
                        fprintf(resultFile, "%s", buff);
                }

                // closing current file
                fclose(f);
        }

// closing resultFile
fclose(resultFile);

return 0;
