| 1. | a. Name the header file, to which the following build in functions belong: i) strcmp() ii) isalpha() iii) isalnum() iv) strcat() b. Will the following program execute successfully? If not, state the reason(s) #include void main() { int s1, s2, num; s1=s2=0; for(x=0;x<11;x++) { cin< if(num>0(s1+=num; else s2=/num; } cout< } c. Write definition for a function SumSequence() in C++ with arguments/parameters-double x and int n. the function should return a value of type double and it should perform sum of the following series: 1/x-3!/x2+5!/x3+7!/x4+9!/x5…….upto n terms (Note: the Symbol ! represents factorial of a number i. e., 4!=5x4x3x2x1) d. Write an interactive program in C++ to read a string and make a table displaying different types of character in the following format: For Example: Input String: The QUICK BROWN fox jumps over the LAZY LITTLE dog. Uppercase Vowels 6 Uppercase consonants 15 Lowercase Vowels 7 Uppercase consonants 13 e. What is this pointer? Explain with example. | 2 1 4 2 1 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Private Members : T_Code of type string No_of_Adults of type integer No_of_Children of type integer Distance of type integer TotalFare of type float Public Members : • A constructor to assign initial values as follows : T_Code with the word “NULL” No_of_Adults as 0 No_of_Children as 0 Distance as 0 TotalFare as 0 • A function AssignFare( ) which calculates and assigns the value of the data member TotalFare as follows : For each Adult Fare (Rs) For Distance (Km) 500 >=1000 300 <1000>=500 200 <500 For each Child the above Fare will be 50% of the Fare mentioned in the above table. For example : If Distance is 750, No_of_Adults = 3 and No_of_Children = 2 Then TotalFare should be calculated as No_of_Adults * 300 + No_of_Children * 150 i.e. 3 * 300 + 2 * 150 = 1200 • A function EnterTraveK ) to input the values of the data members T_Code, No_of_Adults, No_of_Children and Distance; and invoke the AssignFare( ) function. • A function ShowTraveK) which displays the content of all the data members for a Travel.
i. Write the objects of ZOO to a binary file. ii. Read the objects of ZOO from binary file and display them on screen. Class ZOO { char location[20]; int no_of_animals[10]; public: void readdata() { cin>>location; gets(no_of_animals); } void writedata() { cout< } };
