Concept understanding — Decision Control Statements (if, if-else and nested-if)

By default a C program runs its statements one after another, but decision (conditional) control statements let it choose between alternative paths depending on a condition. They are the basis of all decision-making programs.

if statement - executes a block only when its condition is true; if the condition is false the block is skipped.
```
if (condition)
    statement;
```
if-else statement - provides two alternatives: one block runs when the condition is true, the other when it is false.
```
if (condition)
    statement1;
else
    statement2;
```
Nested-if / else-if ladder - an if (or if-else) placed inside another, used to test several conditions in turn. This is how a program picks the largest of three numbers, or grades a value into ranges such as short, average and tall. …

[!TLDR]

The == operator tests two integers for equality; when they match, the if statement executes and the message is printed.

Relational operators compare two operands and give a result that is true (non-zero, i.e. 1) or false (0). The equality operator == returns true only when both operands are equal. In the program x and y are both initialized to 4, so x==y is true (1) and the printf inside the if is executed. A complete standard version is:

#include <stdio.h>

int main(void)
{
    int x = 4, y = 4;
    if (x == y)
        printf("x and y are equal\n"); …
