Suppose we need to specify multiple conditions then we need to use multiple if statements or else if ladder.
void main( )
{
int per;
printf("enter per:\n");
scanf("%d",&per);
if ( per >= 60 )
printf ( "First division" ) ;
else if ( per >= 50 )
printf ( "Second division" ) ;
else if ( per >= 40 )
printf ( "Third division" ) ;
else
printf ( "fail" ) ;
getch();
}
