Example

break-in for loop

We can use break statement with for loop. In the following examples, we can see the usage of break-in “for loop”.

Program 1

When the above code is executed, The following output is displayed

1
2
3
4
5

This is a simple program to display from 0 to 10 positive number. But, When becoming i=5, the break executes and the loop is terminated.

Program 2

When the above code is executed, The following output is displayed

Here, the first natural numbers are:
1
2
3
4
5
The sum is: 15
terminate the program

This program helps to find the sum of the first 10 positive number using sum=sum+i. But, when i==5, loop flow is terminated using break statement.

program 3

When the above code is executed, The following output is displayed

case 1

Enter any number
3                               // you can enter 3 number
enter number: 1
6                               //this is the first number
enter number: 2
7                                //this is a second number
enter number :3
8
Total is: 21            // this is a total of 3 numbers

case 2

Enter any number
5                           // you can enter 5 number
enter number: 1
43                        //this is the first number
enter number: 2
23                        //this is a second number
enter number :3
0                           //this is the third number

In this program, the third number is 0 so the loop is terminated. It shows the total number.

Total is: 131

break in while loop

We can use break statement with while loop. Here is an example of usage of the break-in “while loop”.

Program 1

When the above code is executed, The following output is displayed

Program 2

When the above code is executed, The following output is displayed

Program 3

When the above code is executed, The following output displays

Enter any number
5
enter number :1
45
enter number :1
67
enter number :1
0
Total is :112

Break in Do-while loop

We can use break statement with while loop. Here is an example of usage of the reak-in “while loop”.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i=0;
    do{
        if(i==5){
            break;
             i++;
        }
        printf("%d",i);
        i++;
    }while(i<=10);

getch();
    return 0;
}

When the above code is executed, The following output displays

01234

This is a simple program to display from 0 to 10 positive number. But, When becoming i=5, the break executes and the loop is terminated.

Break  in the switch

We can use switch statement with for loop. Here is an example of uthe sage of switch.

When the above code is executed, The following output is displayed

1. When a value of 1 is entered,this output is displayed.

Enter the value :
1
you have entered value 1:
Exit from the loop

2. When a value of 2 is entered, this output is displayed.

Enter the value :
2
you have entered value 2:
Exit from the loop

3. When a value of 3 is entered, this output is displayed.

Enter the value :
3
you have entered value 3:
Exit from the loop

4. When a value of 4 is entered, this output is displayed.

Enter the value :
5
you have entered value 5:
Exit from the loop

5. When the input is any other number, this message is displayed

Enter the value :
5
your input other than 1,2,3 & 4:
Exit from the loop

You always need to use the break  in a “switch case block” at the end of the case. When that case statement is executed, break terminates the loop.

Otherwise, after a case block is executed, the next case blocks will be executed without the termination of the previous one.

For example, if we don’t use the break after every case block, then the output of this program would be:

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int value;
    printf("Enter the value:\n");
    scanf("%d",&value);
    switch(value)
    {
        case 1:printf("you entered 1:\n");
        //break;
        case 2:printf("you entered 2:\n");
        //break;
        case 3:printf("you entered 3:\n");

        case 4:printf("you entered 4:\n");
         //break;
        default:
            printf("you input other than 1,2,3 & 4");
        break;
        //break;
    }
    printf("\nExit from the loop");
    getch();
    return 0;
}

Enter the value  :
1
you entered  1 :
you entered  2 :
you entered  3 :
you entered  4 :
you input other than 1,2,3 &4:
Exit from the loop
