C Loops Test – 3

1. What is an example of iteration in C?

2. What will be the output of the following C code?

    #include <stdio.h>
    void main()
    {
        char *str = "";
        do
        {
            printf("hello");
        } while (str);
    } 

3. How many times while loop condition is tested in the following C code snippets, if i is initialized to 0 in both the cases?

while (i < n)
         i++;
    ————-
    do
         i++;
    while (i <= n);

4. What will be the output of the following C code?

#include <stdio.h>
void main()
{
    int i = 0;
    while (i < 10)
    {
        i++;
        printf("hi\n");
        while (i < 8) 
        {
            i++;
            printf("hello\n");
        }
    }
}

5. Which loop is most suitable to first perform the operation and then test the condition?

6. What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        int i = 0;
        while (i = 0)
            printf("True\n");
        printf("False\n");
    } 

7. What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        int i = 0, j = 0;
        while (i < 5, j < 10)
        {
            i++;
            j++;
        }
        printf("%d, %d\n", i, j);
    }
