5.1. Introduction to Simple and Compound Statement

In C programming, a statement or an instruction is a basic building block of a program that expresses an action to be carried out. There are two main types of statements: simple statements and compound statements.

Simple Statement:

A simple statement is the most basic type of statement that performs a single action. It typically ends with a semicolon (;).

Example:

#include <stdio.h>

int main() {
    int x = 5;  // Simple statement assigning a value to a variable
    printf("The value of x is %d\n", x);  // Simple statement using printf
    return 0;  // Simple statement with a return statement
}

Compound Statement (or Block):

A compound statement, also known as a block, is a group of simple statements enclosed in curly braces {}. It allows multiple statements to be grouped together and treated as a single unit.

Example:

#include <stdio.h>

int main() {
    int x = 5;  // Simple statement
    {
        // Compound statement (block) begins
        int y = 10;  // Simple statement within the block
        printf("The sum of x and y is %d\n", x + y);  // Another simple statement within the block
        // Compound statement (block) ends
    }
    // y is not accessible here because it is declared within the block
    return 0;
}
