If Else If

I‚Äôm not exactly sure how to do a proper if else if statement in C programming. I‚Äôm also unsure as when to use the curly brackets in the code (I know they‚Äôre not always required. This is my first programming language & I‚Äôm teaching myself so I apologize for my total ignorance. ūüėá If someone could provide a very simple example of an if else if program & kindly walk me through it, I‚Äôd really appreciate it. ~Thanks in advance, Cj

The if statement has the same function as other languages. It has three basic forms: if( expression ) statement OR: if( expression ) statement1 else statement2 OR: if( expression ) statement1 else if( expression ) statement2 else statement3

if (condition1) { // execute if condition1 is true } else if (condition2) { // if condition1 is false, execute if condition2 is true }

if(condition1) { Statements; //executes when condition 1 is true } else if(condition2) { Statements;//executes when condition 2 is true } Note that the curly braces{} are not required when there is only one statement in the if-block or else-block,, more than one statement there we require the curly braces..

As for curly brackets, they are not required if only one statement follows the if-else statement. if (true) std::cout << "Hello"; If you have multiple statements you want to execute based on the evaluation of condition, then you have to group them together using curly braces. if (true) { // statement 1 // statement 2 }

1.We can use curly brackets when there is a code more than one line after if Or else. 2.In all other cases Its is not that much important to use curly brace Eg: If(condition1) { /* code * Some printf statements * Some condition * Increment or decrement */ } else If(condition2) Printf("single line code after if"); else Printf("single code after else");

Based on time & space complexity's Use for loop but its better & recomended to use recursion for a good coder

If its based on curly brackets its similar to the above if else form For nested for loop curly brackets are not required Eg : /* in this case we wont need any curly bracket. */ for(int i=0;i<3;i++) for(int j=0;j<3;j++) { scanf("%d",&a[i][j]); }
