Dear Students,
ATS provides the better
way of Program Learning with experienced faculties of engineering colleges and
Industry Experts. Our team emphasis on the programming concepts with practical
implementations. Some sample program problems of C++ under subject Computer
Science of class XI & XII are given below for your practice
and Expertise. You can bring the solution of any program given below from the
branch of ATS. We assign these programs as problem assignments to our
students and they perfom in front of faculties and get the practical exposer.

using write() and read() function using a binary file.
Find the OUTPUT/ERRORS
1. What is
wrong with the following while loops ( ans how does the correct ones look
like):
(i) int counter =1; (ii)
int counter =1;
while (counter<100) while
(counter <100)
{ cout<<counter<<
“\n”;
cout<<counter<<”\n”;
counter + +;
counter--;
}
2.
Find the errors in the following program. State reasons:
#include<iostream.h>
class A
{ int
a1;
public: int a2;
protected: int a3;
};
class B: public A
{
public:
void func()
{ int
b1,b2,b3;
b1=a1;
b2=a2;
b3=a3;
}
};
class C: A
{
public:
void f()
{ int
c1,c2,c3;
c1=a1;
c2=a2;
c3=a3;
}
};
int main()
{ int
p,q,r,i,j,k;
B 01;
C 02;
p=01.a1; q=01.a2;
r=01.a3; i=01.a1;
j=01.a2; k=01.a3;
return 0;
}
1.
Identify
and explain the error(s) in the following code segment :
float a[] = { 11.02, 12.13, 19.11, 17.41};
float *j, *k;
j = a;
k = a + 4;
j = j * 2;
k = k / 2;
cout << “ *j = “ << *j
<< “, *k = “ << *k << “\n”;
2.
Identify and explain the error in the following program :
#include<iostream.h>
int main()
{
int
x[] = { 1, 2, 3, 4, 5 };
for
(int i = 0; i < 5; i++)
{
cout
<< *x;
x++;
}
return
0;
}
3.
Give the output of the following :
char
*s = “computer”;
for
(int x = strlen(s) – 1; x >= 0; x--)
{
for(int y =0; y <= x; y++) cout << s[y];
cout << endl;
}
4.
Identify the syntax error(s), if any, in the
following program. Also give reason for errors.
void
main()
{
const
int i = 20;
const
int * const ptr = &i;
*ptr++;
int
j= 15;
ptr = &j;
}
5.
What will be the output of following program ?
#include<iostream.h>
void main()
{
char name1[] = “ankur”;
char name2[] = “ankur”;
if (name1 != name2)
cout << “\n both the strings are
not equal”;
else
cout
<< “\n the strings are equal”;
}
6.
Give and explain the output of the following code :
void junk (int, int *);
int main()
{
int i = 6, j = -4;
junk (i, &j);
cout << “i = “ << i << “, j = “ << j
<< “\n”;
return 0;
}
void junk(int a, int *b)
{
a = a* a;
*b
= *b * *b;
}
