Input Output
Most languages have "statements" to perform I/O . Though in C and C++ we use "functions" to perform I/O. C++ also has its own I/O mechanism - the cin and cout objects, declared in the header file iostream.h.
On including iostream.h , the program gets the following 4 objects automatically:
Cin- This object corresponds to the standard input Stream, which by default is the keyboard.

Write a program to find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. The area under a curve between two points can b
Data array A has data series from 1,000,000 to 1 with step size 1, which is in perfect decreasing order. Data array B has data series from 1 to 1,000,000, which is in random order.
Aim: To implement a program to add two complex numbers using constructors. Code: class complex { int real; int img;
Binomial coefficients are the numeric factors of the products in a power of a binomial such as (x + y)n. For example, (x + y)2 = x2 + 2 x y + y2 has the coefficients 1 2 1. Binomia
