Technical
1. Declare a function pointer and call it for the function void fun { printf(“MCA2k11”); }
2. What would be output?main(){ char str[] = “JNUMCA2k11”;
int a;printf(a>10 ? “%5s” : “%s”, str);
}
3. What would be output?
int main()
{ float a = 0.25; if(a < .25) { printf("greater than"); } else if(a == .25) {
printf("equal");
} else { printf("less than"); } }
4. Write a macro print(x, y, z) to print the following.x=4 y=5 z=6main(){
int x = 4, y = 5, z = 6;print(x,y,z);
}5. Explain:
int a = 5; const int *p = &a; int * const p = &a; const int * const p = &a; int const *p = &a;
6. What will be outputmain(){
char *ptr;*ptr = (char *)malloc(30);strcpy(ptr, “JNUMCA”);strcat(ptr, “2k11”); printf(“%s”, ptr);free(ptr);
}7. Explain f:
void (* f)(int, void (*)());8. What will be output
#include<iostream>using namespace std;#define PI 3.14int squareArea(int &a){ return a*=a;}double circleArea(int &r){ return PI*r*r;}int main(){ int a = 10; cout<<squareArea(a)<<endl; cout<<circleArea(a)<<endl; return getchar();
}9. Output:
#include<iostream>using namespace std;class Alpha{
int data;public:
Alpha(int num){
data=num;}Alpha(Alpha &a){
data=a.data;cout<<"copy constructor\n";
}void display(){
cout<<"value of data is "<<data<<endl;}void operator=(Alpha &a){
data=a.data;cout<<"assignment operator"<<endl;
}};int main(){
Alpha a1(37);Alpha a2(2);a2.display();a2=a1;a2.display();Alpha a3(a1);a3.display();
}
10. Write a template function to swap int, char, double values.#include<iostream>using namespace std;//template function definitionmain(){
int a = 5, b = 7;double d = 4.5, e = 5.6;char x = 'x', y = 'y';swapargs(a,b);swapargs(d,e);swapargs(x,y);
}
