Loops in C
Loops in C - Definition and Usage
- In C- Programming the control statement is used for performing looping operations until the given condition is true.
- Control comes out of the loop statements once condition becomes false.
- C loops execute a block of commands for the specific number of times, until a condition is met or satisfied.
- In C-program, there are three different types of control statement as follows:
While loop Statement :
- In C – Programming the while Loop is executed, only when condition is true.
C Syntax
While (condition)
{
statements;
}
Do While Loop Statement :
- In C – Programming the do while Loop is executed at least one time then after executing the while loop for first time, then condition is checked.
C Syntax
do
{
statements;
}
while (condition);
For Loop Statement :
- For loop is used to execute a set of statements repeatedly until a particular condition is satisfied. We can say it as an open ended loop. General format is,
C Syntax
for(initialization; condition ; increment/decrement)
{
statement-block;
}- In for loop we have exactly two semicolons, one after initialization and second after condition.
- In this loop we can have more than one initialization or increment/decrement, separated using comma operator.
- for loop can have only one condition.
