Extend the below program such that when reading the 3 values per record from the file, the values get stored in arrays. We need an array for each data type read per record ( loop counter to store corresponding values at the same index in the 3 different arrays). We need a two dimensional char array. when copying a string to another, we need to use the strncpy function. Once all the data from the input file is read and stored this data into the 3 arrays, open a file for writing ( output.csv) and print the array data to this file (use fprintf). The format written to the file should be one line per record, with each field separated by a comma (‘,’). Close both files. #include char c; int main (int argc, char **argv) { FILE* f; if (argc != 2) { printf("No filename in the argument"); return 1; } f = fopen(argv[1], "r"); if (f == NULL) { printf("The file cannot be opened successfully: %s\n",argv[1]); return 1; } printf("The file has been opened successfully\n\n"); int lines = 0; while( c != EOF) { c = fgetc(f); if(c == '\n') { lines++; } if(c ==EOF) { lines++; } else { printf("%c",c); } } printf("\n\nFile has Total %d Lines.",lines) ; fclose(f); return 0; }
