Final answer:
The argc and argv[] parameters are used in a C program to handle command line arguments. argc represents the number of command line arguments, while argv[] is an array of strings that holds the command line arguments.
Step-by-step explanation:
The argc and argv[] parameters are used in a C program to handle command line arguments. The argc parameter represents the number of command line arguments passed to the program, while the argv[] parameter is an array of strings that holds the actual command line arguments.
For example, consider a C program called myprogram that takes two command line arguments: input.txt and output.txt. In this case, argc would be set to 3 (program name, input file, and output file), and argv[] would contain the strings "myprogram", "input.txt", and "output.txt" respectively.
