Which C++ library is commonly used for vector arithmetic?

int main()

{

  int x,y, z; 

  x=y=z=5; 

  z= ++x || ++y && ++z;

  cout<<x<<y<<z;

   return 0;

}

What will be the output of the following C code?

#include<stdio.h>

int main()

{

int x=5;

if(x<1)

  printf("hello");

if(x==5)

   printf("hi");

else

   printf("no");

return 0;

}

What operation does the following function "func" perform on the array?

What is the output of the following C code?

int main()

{

  int m=10, *n, **o, ***p;

  n=&m;

  o=&n;

  p=o;

  printf("%d %d %d %d", m, *n, **o, ***p);

}

What is Spaghetti programming?

#include <stdio.h>

int *A, stkTop;

int stkFunc (int opcode, int val)

{

static int size=0, stkTop=0;

switch (opcode)

{

case -1:

size = val;

break;

case 0:

if (stkTop < size ) A[stkTop++]=val;

break;

default:

if (stkTop) return A[--stkTop];

}

return -1;

}

int main()

{

int B[20];

A=B;

stkTop = -1;

stkFunc (-1, 10);

stkFunc (0, 5);

stkFunc (0, 10);

printf ("%dn", stkFunc(1, 0)+ stkFunc(1, 0));

}

#include class Base { virtual void method() {std::cout << "from Base" << std::endl;} public: virtual ~Base() {method();} void baseMethod() {method();} }; class A : public Base { void method() {std::cout << "from A" << std::endl;} public: ~A() {method();} }; int main() { Base* base = new A; base->baseMethod(); delete base; return 0; }

What will be the output of the following C++ code?

#include <iostream>

#include <memory>

       pair <int*, ptrdiff_t> result = get_temporary_buffer<int>(4);

if (result.second > 0)

{

           uninitialized_copy (numbers, numbers + result.second, result.first);

           sort (result.first, result.first + result.second);

for (int i = 0; i < result.second; i++)

cout << result.first[i] << " ";

           return_temporary_buffer (result.first);

}

return 0;
