P.T.O. 91

SECTION A

[Only for candidates, who opted for C++]

2 1. 1 2

1. (b) Write the names of the correct header files, which must be included

in the following C++ code to compile the code successfully:

void main() char L[]="CS 2018"; int N=strlen(L); cout<<L[N-1];

1. Rewrite the following C++ program after removing any/all syntactical error(s). Underline each correction done in the code: Note: Assume all required header files are already included in the program. <math>\#define Area(L,B) = L*B</math> structure Recta int Length, Breadth; }; void main() Recta <math>R = [10, 15];</math> cout<<Area(Length.R, Breadth.R);</pre> }
2. Note: Assume all required header files are already included in the program. void Alter(char *S1, char *S2) char *T; <math>T=S1;</math> <math>S1=S2;</math> <math>S2=T;</math> cout<<S1<<"&"<<S2<<end1; } void main() t char X[]="First", Y[]="Second"; Alter(X,Y); cout<<X<<"*"<<Y<<end1; }
