Understanding If-Else Statement The if-else statement extends the functionality of the if statement by allowing an alternative set of instructions to be executed when the if condition is false. Syntax and Structure The syntax for an if-else statement in C is: if (condition) { // block of ...
Mechanism of if-else statement in C Initiated by the “if” keyword, the statement is enclosed in parentheses containing an evaluative condition, typically a Boolean expression capable of being true or false. When the condition enclosed within the parentheses is assessed as true, the code snippet...

C If Else statement is kind of an extension toC IfStatement. In C If statement, we have seen that execution of a block of statements depends on a condition. In If Else statement, we have one more block, called else block, which executes when the condition is false. So, in C if-els...
Curly braces rule is same as we have discussed in last chapter (if statement syntax in C/C++), curly braces are not required, if there is only one statement. Consider the given example: #include<stdio.h>intmain(){inta=10;intb=-10;intc=0;if(a==10)printf("First condition is true\...
This type of if statement is used when you have more than one test conditions and blocks to execute. Syntax if(test-condition1) { Block1; } else if(test-condition2) { Block2; } else if(test-condition3) { Block3; } ... else ...

I’m not exactly sure how to do a proper if else if statement in C programming. I’m also unsure as when to use the curly brackets in the code (I know they’re not always required. This is my first programming language & I’m teaching myself so I apologize for my total ignorance...
