1) Which of the following statements are correct about the below C-program?
#include<stdio.h>
int main()
{
    int x = 10, y = 100%90, i;
    for(i=1; i<10; i++)
    if(x != y);
        printf("x = %d y = %d\n", x, y);
    return 0;
}
1 :    The printf() function is called 10 times.
2 :    The program will produce the output x = 10 y = 10
3 :    The ; after the if(x!=y) will NOT produce an error.
4 :    The program will not produce output.
2) What will be the output of the program?
#include<stdio.h>
int main()
{
    int k, num=30;
    k = (num>5 ? (num <=10 ? 100 : 200): 500);
    printf("%d\n", num);
    return 0;
}
3) Point out the error in the following program.
#include<stdio.h>
int main()
{
    struct emp
    {
        char name[20];
        float sal;
    };
    struct emp e[10];
    int i;
    for(i=0; i<=9; i++)
        scanf("%s %f", e[i].name, &e[i].sal);
    return 0;
}
4) The keyword used to transfer control from a function back to the calling function is
5) Which of the following statements are correct about the function?
long fun(int num)
{
    int i;
    long f=1;
    for(i=1; i<=num; i++)
        f = f * i;
    return f;
}
6) Which of the statements is correct about the program?
#include<stdio.h>

int main()
{
    float a=3.14;
    char *j;
    j = (char*)&a;
    printf("%d\n", *j);
    return 0;
}
7) Will the program compile in Turbo C?
#include<stdio.h>
int main()
{
    int a=10, *j;
    void *k;
    j=k=&a;
    j++;
    k++;
    printf("%u %u\n", j, k);
    return 0;
}
8) Which of the following statements are correct about an array?
1:    The array int num[26]; can store 26 elements.
2:    The expression num[1] designates the very first element in the array.
3:    It is necessary to initialize the array at the time of declaration.
4:    The declaration num[SIZE] is allowed if SIZE is a macro.
9) The library function used to find the last occurrence of a character in a string is
10) If char=1, int=4, and float=4 bytes size, What will be the output of the program ?
#include<stdio.h>

int main()
{
    char ch = 'A';
    printf("%d, %d, %d", sizeof(ch), sizeof('A'), sizeof(3.14f));
    return 0;
}
