Write a single instruction that will store an EVEN random integer between 54 and 212 inclusive in the variable myran. (NOTE only generate EVEN random numbers)
1950Given the following seqment of code containing a group of nested if instructions: y = 9; if ((x==3) || (x == 5)) y++; else if (x == 2) y *= 2; else if (x == ) y-= 7; else y = 8; if the value of x is 4 before the nested IFs are executed, what is the value of y after the nested IFs are executed?
2029Given the following seqment of code containing a group of nested if instructions: y = 9; if ((x==3) || (x == 5)) y++; else if (x == 2) y *= 2; else if (x == 4 ) y-= 7; else y = 8; Enter a segment of code (without any IF statements) that does exectly the same thing using the switch structure.
1 3720Given the following function definition: int doit(int &x, int y, int &z) { x = 3*x; y = y + 5; z = x+y; return z - 4; } int a = 5, b = 7, c = 9, d = 11; d = doit(a,b,c);

2632In OverLoading concept,Why they are not consider return value and why they are consider only parameters in method? For ex: public int Add(int a,int b){...} public String Add(int a,int b){...}
1 3331Write a program and call it sortcheck.cpp which receives 10 numbers from input and checks whether these numbers are in ascending order or not. You are not allowed to use arrays. You should not define more than three variables

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
