Answer 1

Explanation:

The basic input/output functions are getchar , putchar , puts , scanf and printf . The first two functions, getchar and putchar, are used to transfer single characters.

Answer 2

Concept:

A large program in C can be broken down into basic building blocks called functions. A function includes a collection of programming statements enclosed by { }.

Given:

#include <stdio.h>

static void show();               //function declaration

int main()

{

printf("ROCKET ");

show();                                 //function call

return 0;

}

static void show()                //function definition

{printf("STATIC");

}

Find:

Find the output of the given statement.

Solution:

In C, a function has three aspects:

1. Function declaration - It tells about the function name, return type, and function parameters. A function should be declared globally.

Syntax: return_type function_name (argument list);

2. Function call - A declared function gets executed when it is called.

Syntax: functions_name(argument_list);

3. Function definition -

It includes the actual statements which are to be executed.

Syntax: return_type function_name (argument list) {function body;}

in the given code, there is one function named 'show'. It is called after the printf("ROCKET "); statement, therefore ROCKET will get printed first and then STATIC will be printed.

Output:

ROCKET STATIC
