How can an argument be passed to a function during a call?

Arguments in a C/C++ function are passed when calling the function, enclosed in parentheses after the function name, listing the values or variables that correspond to the function's parameters.

Example:

#include <iostream>

void greet(const char* name) {
    std::cout << "Hello, " << name << "!" << std::endl;
}

int main() {
    greet("Alice"); // Passing a string literal as an argument
    return 0;
}

Here, the argument "Alice" is passed to the greet function during the call. Arguments can be literals, variables, expressions, etc.
