Tutorial Decision or Branch in C Programming Langauge

We can make some decisions with C programming language. The decisions in C programming language used to execute some codes and ignore some codes depending on the given condition is true or false. Now, I will tell you how to make decisions or branch in C programming language. We can make decision with if, if...else, and switch...case.

If statement

Basic If syntax : 

   

          if(text expression) {

         statement to be executed if it is true;

         }

       

For example:

Try the code. If the statement is true then it will show the result.

If...else Statement

Basic If...else syntax :

          If (text expression) {

            statements to be executed if expression is true;

        }

        else {

            statements to be executed if expression is false;

        }

        

For example:

Try the code. If the result of num divided by 2 not zero than the num is odd.

If the result of num divided by 2 is zero, then the num is even.

Switch...case Statement

Basic switch...case syntax:

          switch(text expression) {

          case 1:

                code to be executed if text expression equals to case 1;

                break;

          case 2:

                code to be executed if text expression equals to case 2;

                break;

                .

                .

                .

                .

          default:

               code to be executed if text expression doesn't equals to any cases;

          }

That's the explanation about decision and branch in C programming language. Now, you can try your own code to make decision and branch. Have a great time with coding!
