IF AND ELSE STATEMENT IN C

If and Else Statement in C

Hello guys,

In the last time we learn about the format specifires and datatypes in C. In this lecture we will learn about the If and else statements in C.

 

Firstly understand the meaning of if and else we use it in the general life. For example “if tomorrow is holiday we will plan for the tour else we will continue our work”.

Here else is not much important, in the same manner in C else has not much importance in if and else statement. But we use it for clearing the programs meaning.

Let see the above example here condition is applied i.e. tomorrow is holiday

Like these conditions are in C

Let us understand these conditions

 

The syntax is

if()

{

                //code;

}

else

{

                //code;

}

Lets see the program

 

Here we can see that IF and ELSE statement.

Here we assigned the value 1 in variable named as n. 

we simply used equal condition for execution of the program, we already assigned the value in the variable so it will continue the program and ignore the else statement.

When we enters in the if statement compiler checks the condition, if the condition is true then the code from if statement runs i.e. It will continue the program, if condition is false it will jump to the else statement.

If you want to add more conditions than one then user have to use else if statement.

The syntax is as follow

if()

{

                //code;

}

else if ()

{

                //code;

}

else

{

                //code;

}

Here the compiler simply check the conditions if the condition is true it will continue the program, else the compiler will jump from that code and will continue execution

 

Exercise

You have to make the program based on the multiple conditions.

Program

Days	Paper
Monday	Math
Tuesday	English
Thursday	Computer science
Wenesday	History
Friday	Geography
Saterday	Biology

 

In the above table 6 days shedulde and the paper are given.

You have to take input from the user in the form of number declared specific number for the day.

Then simply you have to print the exact subject shedulded on the day.

If user enters wrong statement then simply print “Invalid input”.

Output

On Monday the paper was of Math

 

I hope you have absorbed the information from this post.

Thanks for reading
