To execute a single '''statement'''.

To execute group of '''statements'''.

We will do this through examples.

We will also see some common errors and their solutions.

'''Ubuntu Operating system''' version 11.10.

'''gcc''' and '''g++ Compiler''' version 4.6.1

|-
| style="background-color:transparent;border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide 4

A '''statement''' in a program controls the flow of program execution.

It helps to make decision on, what code is to be executed.

We can check the conditions, whether true or false.

We can execute a single statement or a group of statements.

|-
| style="background-color:transparent;border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide 5
| style="background-color:transparent;border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Let us understand the flow of if statements.

Here, if the condition is true,then '''statement1''' will be executed.

If the condition is false then '''statement2''' will be executed.

|-
| style="background-color:transparent;border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide 6
| style="background-color:transparent;border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now we will see the flow of else if '''statement''',

Here, if '''condition1''' is true then '''statement1''' will be executed.

If '''condition1''' is false then it will check for another condition that is '''condition2'''.

If '''condition2''' is true, then '''statement3''' will be executed.

If '''condition2''' is false, then '''statement2''' will be executed

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Let us switch to the file ifstmt.c

| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now Let us move on to our program.

I have already typed the code on the editor.

So let me open it.

Note that our filename is '''ifstmt.c'''

In this program we will calculate the sum of two numbers and will check a few conditions.

This is our '''header file.'''

|-

| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Here we have declared three integer '''variables'''

'''a, b and sum.'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Highlight

'''printf("Enter the value of a and b is \n"); '''

'''scanf("%d%d",&a,&b);'''

User will enter the values of a and b.

The values will be stored in '''variable a''' and '''variable b.'''

|-

It then stores the result in the given '''variable.'''

The''' format specifier '''in the''' scanf() '''helps to know the type of data.

Like here we have %d it denotes that we are dealing with integer data type.

We will store the result in '''sum.'''

Here, we check the condition whether '''sum''' is greater than 20.

If the condition is true,

then we print '''Sum''' is greater than 20.

Let me clear the prompt.
To compile type

'''g++ space ifstmt.cpp space -o space if1'''

Here we have '''if1''' because we don't want to overwrite the output parameter '''if''' for the file '''ifstmt.c'''

Now Press '''Enter'''

To execute type

'''./if1'''

And Press '''Enter'''

Enter the value of a and b.

I will give the values as 20 and 10.

The output is displayed as,

Sum of a and b is 30.

Sum is greater than 20.

This brings us to the end of this tutorial.

Now come back to our slides.
