8escs01 problem solving through programming unit-2: c programming basics

Syntax:

if(Condition1) { Statements 1; } else if(Condition 2) { Statements 2; } else if(Condition 3) { Statements 3; } else { else statements; }

CONTROL STATEMENTS

void main ()
{ int a = 100;
if( a == 10 )
{ printf("Value of a is 10\n" ); }
else if( a == 20 )
{ printf("Value of a is 20\n" ); }
else if( a == 30 )
{ printf("Value of a is 30\n" ); }
else
{ printf("None of the values is matching\n" ); } printf("Exact value of a is: %d\n", a );
}

BRANCHING STATEMENTS – ELSE..IF STATEMENT
Example:
#include
Output:
None of the values is matching Exact value of a is: 100

CONTROL STATEMENTS

BRANCHING STATEMENTS – NESTED IF STATEMENT

• An if .. else statement is placed inside another if..else statements, this is known as nested if..else statements.
• These are used when series of decisions are involved.

Syntax:	Flow Diagram:
if( Condition 1) { /* Executes when the condition 1 is true */ if(Condition 2) { /* Executes when the condition 2 is true */ } } else { /* Executes

CONTROL STATEMENTS

void main ()
{
int a = 100;
int b = 200;
if( a == 100 )
{
if( b == 200 )
{
printf("Value of a is 100 and b is 200\n" );
}
}
printf("Exact value of a is : %d\n", a ); printf("Exact value of b is : %d\n", b );
}
