If-else statement in C.

Friends now we are Going To start If-Else.

Some time we have to make some decision in our program for those we have If statement. If statement work in such a way

1.

if (condition)
    statement;

if our condition is true then our statement will run

2.

if (condition)
    statement_1;
else
    statement_2;

In this case if our condition is true then our statement_1 will run and if our condition is false then our statement_2 will run.

3.

if (condition)
{
    statement_1;
    statement_2;
    statement_.....;
}
else
    statement_n;

In this case if our condition is true then all our statements written in if ( or we can say all statement in that pair of {} ) will run .

NOTE : If we have more than one statement than pair of {} is necessary.

If our condition is false then our statement_n will run. which was written in else.

3.

if (condition)
{
    statement_1;
    statement_2;
    statement_.....;
}
else
{
    statement_1;
    statement_2;
    statement_.....;
}

In this case if our condition is true then all our statements written in if ( or we can say all statement in that pair of {} after if ) will run .

If our condition is false then our all statements written in else will run. which was written in else. ( or we can say all statement in that pair of {} after else ) will run .

NOTE : If we have more than one statement than pair of {} is necessary.

In our next Post  we will code some programe. Based on If-else statements and do some example.
