do…while Loop In C

As discussed before, loop contains three part

• Intialization
• Condition Checking
• Incrementation Or Decrementation

do…while loop is also called exit control loop, it means that the statement of loop are always executed once even if the condition is false. In this while is ended by semicolon(;).

Syntax

variable=0;
do
{
	//statement
	variable++; or variable--;
	//increment or decrement
}while(condition);

Example is given below

#include<stdio.h>
#include<conio.h>

void main()
{
    int i = 10;     // declaration and initialization at the same time
	
    clrscr();

    do // do contains the actual code and the updation
    {
        printf("i = %d\n",i);
        i = i-1;    // updation
    }while(i > 0);
    
    printf("\n\The value of i after exiting the loop is %d\n\n", i);
    
    getch();
}

OutPut

i= 10
i= 9
i= 8
i= 7
i= 6
i= 5
i= 4
i= 3
i= 2
i= 1


The value of i after exiting the loop is 0
