What is the limit for number of functions in a C++ program?
1) main() in C program is also a function. 2) Each C program must have at least one function, which is main(). 3) There is no limit on number of functions; A C program can have any number of functions. 4) A function can call itself and it is known as “Recursion“.
How do you check if a number is between a range in C++?
If x is in range, then it must be greater than or equal to low, i.e., (x-low) >= 0. And must be smaller than or equal to high i.e., (high – x) <= 0. So if result of the multiplication is less than or equal to 0, then x is in range.
What is Max float C++?

How many functions are there in C++?
Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.
What is the maximum value of double in C++?

What is the largest double in C++?
The C++ double can hold floating-point values of up to 15 digits taking up a space of 8 bytes in the memory. The range of the values that can be stored in a double type variable is 1.7E – 308 to 1.7E + 308.
How do you initialize a string in CPP?
