11. 11With respect to following “for” loops in C, pick the best statement Assume that there is a prior declaration of 'i' in all cases
    for (i < 10; i = 0 ; i++) // (i)
    for (i < 10; i++ ; i = 0) // (ii)
    for (i = 0; i < 10 ; i++) // (iii)
    for (i = 0; i++ ; i < 10) // (iv)
    for (i++; i = 0 ; i < 10) // (v)
    for (i++; i < 0 ; i = 10) // (vi)

    1. AAll the above “for” loops would compile successfully
    2. BAll the above “for” loops would compile successfully. Except (iii), the behaviour of all the other “for” loops depend on compiler implementation
    3. COnly (iii) would compile successfully
    4. DOnly (iii) and (iv) would compile successfully.
    5. EOnly (iii) and (iv) would compile successfully but behaviour of (iv) would depend on compiler implementation.
12. 12What’s going to happen when we compile and run the following C program?
    #include "stdio.h"
    
    int main()
    {
    int i = 1, j;
    for ( ; ; )
    {
    if (i)
    j = --i;
    if (j < 10)
    printf("GeeksQuiz", j++);
    else
    break;
    }
    return 0;
    }

    1. ACompile Error
    2. BNo compile error but it will run into infinite loop printing GeeksQuiz.
    3. CNo compile error and it’ll print GeeksQuiz 10 times
    4. DNo compile error but it’ll print GeeksQuiz 9 times
13. 13What’s going to happen when we compile and run the following C program?
    #include "stdio.h"
    int main()
    {
    int j = 0;
    for ( ; j < 10 ; )
    {
    if (j < 10)
    printf("Geeks", j++);
    else
    continue;
    printf(“Quiz”);
    }
    return 0;
    }
    

    1. ACompile Error due to use of continue in for loop
    2. BNo compile error but it will run into infinite loop printing Geeks.
    3. CNo compile error and it’ll print GeeksQuiz 10 times followed by Quiz once.
    4. DNo compile error and it’ll print GeeksQuiz 10 times
14. 14What will be the output of the following C code?
    #include <stdio.h>
    main( )
    {
    int i;
    for ( i=0; i<5; i++ )
    {
    int i = 10;
    printf ( "%d ", i );
    i++;
    }
    return 0;
    }

    i = 3;
    else

    printf("%d", i);
    return 0;
