C Language: break and continue statement examples

Question:1
Write a c program to take input for numbers, calculate and print their sum, the program should get terminated when 0(zero) is entered?
Sol:

#include <stdio.h>
int main()
{
    int n,s=0;
    while(1) //for(;;)
    {
        printf("Enter number to add, to end enter 0 (zero) ");
        scanf("%d",&n);
        if(n==0)
            break;
        s=s+n;
    }
    printf("Sum = %d\n",s);
    return 0;
}

Output:

Enter number to add, to end enter 0 (zero) 2
Enter number to add, to end enter 0 (zero) 3
Enter number to add, to end enter 0 (zero) 6
Enter number to add, to end enter 0 (zero) 5
Enter number to add, to end enter 0 (zero) 0
Sum = 16

Question:2
Write a C program to take input for numbers, calculate and print their product. The program should get terminated when zero(0) is entered.
Sol:

#include <stdio.h>
int main()
{
    int n,p=1;
    while(1) //for(;;)
    {
        printf("Enter number , to end enter 0 (zero) ");
        scanf("%d",&n);
        if(n==0)
            break;
        p=p*n;
    }
    printf("Product = %d\n",p);
    return 0;
}

Output:

Enter number , to end enter 0 (zero) 2
Enter number , to end enter 0 (zero) 3
Enter number , to end enter 0 (zero) 6
Enter number , to end enter 0 (zero) 0
Product = 36

Question:3
Write a C program to take input for numbers, count and print total +ve entered numbers. The program should get terminated when zero(0) is entered. (Program can be terminated using any value)
Sol:

#include <stdio.h>
int main()
{
    int n,p=0;
    while(1) //for(;;)
    {
        printf("Enter number , to end enter 0 (zero) ");
        scanf("%d",&n);
        if(n==0)
            break;
        if(n>0)
            p++;
    }
    printf("Total +ve elements  = %d\n",p);
    return 0;
}

Output:

Enter number , to end enter 0 (zero) 2
Enter number , to end enter 0 (zero) 3
Enter number , to end enter 0 (zero) 6
Enter number , to end enter 0 (zero) -9
Enter number , to end enter 0 (zero) 6
Enter number , to end enter 0 (zero) 0
Total +ve elements = 4

Question:4
Write a C program to take input for numbers, count and print total -ve entered numbers. The program should get terminated when zero(0) is entered. (Program can be terminated using any value)
Sol:

#include <stdio.h>
int main()
{
    int n,p=0;
    while(1) //for(;;)
    {
        printf("Enter number , to end enter 0 (zero) ");
        scanf("%d",&n);
        if(n==0)
            break;
        if(n<0)
            p++;
    }
    printf("Total -ve elements  = %d\n",p);
    return 0;
}

Output:

Enter number , to end enter 0 (zero) 2
Enter number , to end enter 0 (zero) 3
Enter number , to end enter 0 (zero) 9
Enter number , to end enter 0 (zero) -8
Enter number , to end enter 0 (zero) -7
Enter number , to end enter 0 (zero) -36
Enter number , to end enter 0 (zero) -5
Enter number , to end enter 0 (zero) 0
Total -ve elements = 4

Question:5
Write a C program to take input for numbers, calculate and print their sum of all +ve entered numbers. The program should get terminated when zero(0) is entered.
Sol:

#include <stdio.h>
int main()
{
    int n,s=0;
    while(1) //for(;;)
    {
        printf("Enter number , to end enter 0 (zero) ");
        scanf("%d",&n);
        if(n==0)
            break;
        if(n>0)
            s=s+n;
    }
    printf("Sum of all -ve elements  = %d\n",s);
    return 0;
}

Output:

Enter number , to end enter 0 (zero) 2
Enter number , to end enter 0 (zero) 3
Enter number , to end enter 0 (zero) 6
Enter number , to end enter 0 (zero) -9
Enter number , to end enter 0 (zero) 0
Sum of all -ve elements = 11
