C program. Finish the following TODO segments:   // TODO: Spawn a child process   ??? = ???;   // CHILD CODE   // TODO: Conditional for child only   if( ??? ){     printf("Child redirecting output to '%s', then exec()'ing\n",            output_file);     // TODO: Open output_file for writing, same options as in switch_stdout.c     int out_fd = ???         // TODO: Copy out_fd to standard output FD table entry     d??? ( ??? );         // TODO: Execute the command in child_argv[] replacing this process     exec??( ??? );     printf("exec() seems to have failed...\n"); // should not reach this     exit(1);   }

Please help me modify my code according to the error prompt #include <stdio.h> void processData(const char* inputFilePath, const char* outputFilePath) {    FILE* inputFile = fopen(inputFilePath, "r");    FILE* outputFile = fopen(outputFilePath, "w");        int n;    fscanf(inputFile, "%d", &n); // Read the number of data points        fprintf(outputFile, "%d\n", n); // Write the number of data points to output        int value;    for (int i = 0; i < n; i++) {        fscanf(inputFile, "%d", &value); // Read the data point                int squaredValue = value * value; // Compute the square of the data point                fprintf(outputFile, "%d\n", squaredValue); // Write the squared value to output    }        fclose(inputFile);    fclose(outputFile);} int main() {    processData("input_file.dat", "output_file.dat");    return 0;}

Through this programming assignment, the students will learn to do the following:  Practice processing command line arguments. Perform basic file I/O. Use structs, pointers, and strings. Use dynamic memory. This assignment asks you to sort the letters in an input file and print the sorted letters to an output file (or standard output) which will be the solution. Your program, called codesolve, will take the following command line arguments: % codesolve [-o output_file_name] input_file_name Read the letters in from the input file and convert them to upper case if they are not already in uppercase. If the output_file_name is given with the -o option, the program will output the sorted letters to the given output file; otherwise, the output shall be to standard output.  In addition to parsing and processing the command line arguments, your program needs to do the following: You need to construct a doubly linked list as you read from input. Each node in the list will link to the one in…
