Control Statements in C++ with Examples

Control Statements in C++:

In C++, Control Statements are usually jumped from one part of the C++ code to another depending on whether a particular condition is satisfied or not. There are three types of C++ Control Statements are given as follows:

1. Sequence Statement

2. Selection Statement

3. Loop Statement

Types of Control Statements in C++:

if-else statement:

if-else statement is used to execute a statement block. It has the following syntax:

if(expression is true
{
action 1;
}
else
{
action 2;
}

​x
 
if(expression is true{action 1;}else{action 2;}

switch statement:

It is a multiple multiple-branching statement where based on a condition, the control is transferred to one of the many possible points. It has the following syntax:

switch(expression)
{
case1:
{
action 1;
}
case 2:
{
action 2;
}
case 3:
{
action 3;
}
default:
{
default statement;
}
}

switch(expression){case1:{action 1;}case 2:{action 2;}case 3:{action 3;}default:{default statement;}}

for statement:

for is an entry-controlled loop. It is used when an action is to be repeated for a predetermined time. It has the following syntax:

for(initial value; test condition; increment or decrement)
{
action 1;
}

xxxxxxxxxx
 
for(initial value; test condition; increment or decrement){action 1;}

while statement:

It is also a loop control structure but it’s an entry-controlled loop. It has the following syntax:

while(condition is true)
{
action 1;
}
action 2;

xxxxxxxxxx
 
while(condition is true){action 1;}action 2;

do-while statement:

do-while is an exit-controlled loop based on a condition, the control is transferred back to a particular point in the program. It has the following syntax:

do
{
action;
}
while(condition is true);
action 2;

xxxxxxxxxx
 
do{action;}while(condition is true);action 2;
