MCQs almost past some new which can be solved with basic programming knowledge.

1. #include <iostream>   5marks
using namespace std;

int main() {

int a[6]={2,1,3,15,20,50};
int i=++a[1];
int j=a[1]++;
int k=a[i++];
int l=a[--i]*i;
int m=a[++i]-1;
couti" "j" "k" "l" "m" ";

    return 0;
}
2. Bitwise operators to mention

3. 

int A[5] = {1 , 2, 3, 4};

int i;

for (i=0; i<5; i++)

{

A[i] = 2*A[i];

cout A[i] " ";

}

4.

What will be the output of the following; (5 marks)

void main()

{

union Num

{

int ValueI;

float ValueF;

double ValueD;

char ValueC;

};

Num TestVal = {100};

cout"Integer =" TestVal.ValueIendl;

TestVal.ValueF = 2.123;

cout "Float=" TestVal.ValueFendl;

cout"Uninitialzed double =" TestVal.ValueD endl;

cout"Some rubbish???"endl;

TestVal.ValueC = 'U';

cout"character=" TestVal.ValueCendl;

}

5.

#include <iostream.h>

main ()

{

int y[10] = {10,20,30,40,50,60,70,80,90,100};

int *yptr, i;

yptr = y;

cout*(yptr+1*2)endl;

}
