1. (a) What is difference between Type Casting and Automatic Type Conversion? Also, give a suitable C++ to illustrate both.
Ans. Explicit Type Casting is used to convert value of one type to another type for example
float x=(float) 3 / 2; // 1.5 will be assigned as result, because 3 is converted into 3.0 Automatic Type Conversion is the type conversion done by the compiler wherever required. e. g. float x=3/2; //here 1.0 will be assigned as result, because 1 is automatically converted in 1.0
1. (b) Write the names of the header files, which is/are essentially required to run/execute the following C++ code:
void main() 1
{char CH,Text[ ]=”+ve Attitude”;
for(int i=0;Text[ i]=’\0’’i++)
if(Text[i]==’ ‘)
cout<<endl;
else {CH=toupper(Text[i]);
cout<<CH;
}
}
Ans. Required header files are iostream.h and ctype.h
1. (c) Rewrite the following program after removing the syntactical errors (if any). Underline each correction.
include<iostream.h>
typedef char[80] String;
void main( )
{String S=”Peace”;
int L=strlen(S);
cout<<S<<’ has ‘<<L<<’characters’<<endl;
}
Ans.
#include<iostream.h>
#include<string.h>
typedef char [80] String;
void main( )
{
String S=”Peace”;
int L=strlen(S);
cout<<S<<” has “<<L<<” characters”<<endl;
}
1. (d) Find the output of the following program:
#include<iostream.h>
void SwitchOver(int A[ ], int N, int Split)
{ for (int K=0; K<N; K++)
if(K<Split)
A[K]+=K;
else
A[K]*=K;
}
void display(int A[ ], int N)
{ for(int K=0; K<N; K++)
(K%2==0) ? cout<<A[K]<<”%” : cout<<A[K]<<endl;
}
void main( )
{ int H[30, 40, 50, 20, 10, 5};
SwitchOver(H,6,3);
Display(H, 6);
}
Ans.cout<<endl;
}
}
