Break and continue keywords in c programming

Explanation of break and continue in c programming language by examples and questions and answers

break:

It is keyword of c programming. Task of this keyword is to bring the control from out of the loop in the case of looping. For example:

#include<stdio.h>

int main(){

    int i;

    

    for(i=0;i<=4;i++){

         printf("%d",i);

         break;

         printf("Label 1");

    }

    printf("Label 2");

return 0;        

}

Output: 0Label2

Another task of break keyword is to switch the control from one case to another case in case of switch case control statement. For example:

#include<stdio.h>

int main(){

    int i=0;

    ++i;

    switch(i){

         case 1:printf("case 1");

         case 2:printf("case 2");break;

         case 3:printf("case 3");

         default: printf("default");

    }

return 0;        

}

Output: case 1case 2

In any other case we cannot use break keyword.

#include<stdio.h>

int main(){

    float a=5.5f;

    if(a==5.5){

         printf("equal");

    }

    else{

         break;

    }

return 0;        

}

Output: Compilation error

continue:

It is keyword of c and task of this keyword is to transfer the control of program at the beginning of loop. For example:

(a)

#include<stdio.h>

int main(){

    int i=5;

   

    do{

         printf("%d",i);

         continue;

         i++;

    }

    while(i<=10);

    return 0;  

}

Output: Infinite loop

(b)

#include<stdio.h>

int main(){

    int i=5;

  

    do{

         printf("%d",i);

         continue;

         i++;

    }

    while(i<=10);

    return 0;  

}

Output: Infinite loop

Except looping, we cannot use continue keyword.

#include<stdio.h>

int main(){

    int x;

    scanf("%d",&x);

   

    switch(x){

    case 1:printf("1");break;

    case 2:printf("2");continue;

    default:printf("3");

    }

    return 0;  

}

Output: Compilation error
