C JUMP STATEMENTS - Learn2Done

In C language there are 4 types of jump statements:

Break Statement
Continue Statement
Goto Statement
Return Statement

Break Statement: Break statement is used to terminate the loops like for, while, do-while from the subsequent execution, it also terminates switch statement.

syntax:

break;

Example:

// Program to demostrate break statement.

# include <stdio.h>
# include <conio.h>
void main()
{
    int num=5; // initializing the variable
    while(num>0)
        {
           if(num==3)
           break;
           printf("%d",num);
           num--;
        }
}

Output:

5 4

Continue Statement: Continue statement is used to continue the next iteration of a loop, so the remaining statements are skipped within the loop.

Syntax:

continue;

Example:

// Program to demostrate continue statement.

# include <stdio.h>
# include <conio.h>
void main()
{
    int num=1; // initializing the variable
    for(i = 0; i<= 10; i++)
        {
           if(i==5 || i==6)
           {
               printf("\n Skiping %d\n",i);
               continue;
           }
        printf("%d",i);
        }
}

Output:

0 1 2 3 4
Skiping 5
Skiping 5
7 8 9

Goto Statement: goto statement is used to transfer the normal flow of a program to the specified label in the program.

Note => The use of goto statement should be avoided as it usually violets the normal flow of execution.

Syntax:

{
    ......
    goto sos
    ......
    ......
    sos:
    statements;
}

Example:

// Program to demostrate goto statement.

# include <stdio.h>
# include <conio.h>
void main()
{
    int num=1; // initializing the variable
    for(i = 0; i<= 10; i++)
        {
           if(i==5)
           {
               goto sos;
           }
        printf("%d",i);
        }
    sos:
    printf("\n Now, this is 5");
}

Output:

0 1 2 3 4
Now, this is 5

Return Statement:

Return Statement: Return statement is used to end or terminate a function immediately with or without value and continues the flow of program execution from where it was called.

The function declared with void type does not return any value.

Syntax:

return; 
or
return value;

Example:

// Program to demostrate return statement.

# include <stdio.h>
# include <conio.h>
void main()
{
    int sum = sum();
    printf("Sum of digits from 1 to 10 = %d\n",sum);
    
}
int sum()
{
    int sum = 0;
    int i;

    for( i = 0; i <= 10 ; i++) {
        sum += i;
    }

    return sum;
}

Output:

Sum of digits from 1 to 10 = 55
