First, let us learn how to find Highest Common Factor (HCF).Highest Common Factor (HCF)The greatest number divides each of the two or more numbers is called HCF or Highest Common Factor. It is also called as Greatest Common Measure(GCM) and Greatest Common Divisor(GCD).For example, What is the HCF of 12 ... Read More

Functions are broadly classified into two types, which are as follows −Predefined functionsUser defined functionsPredefined (or) library functionsThese functions are already defined in the system libraries.Programmer will reuse the already present code in the system libraries to write error free code.But to use the library functions, user must be aware ...

An expression is a combination of operators and operands which reduces to a single value. An operation is performed on a data item which is called an operand. An operator indicates an operation to be performed on data.For example, z = 3+2*1z = 5Primary expressions − It is an operand ... Read More

A ‘C’ program contains executable statements. A compiler helps to translate the executable statements into machine language.When a user runs the program, he/she machines the language statements which are executed by the compiler.Types of executable statementsThe types of executable statements in C language are as follows −Input – output statementsAssignment ...

"Recursive function" is something which calls itself again in the body of the function.For example, A function fact ( ), which computes the factorial of an integer ‘N’, which is the product of all whole numbers from 1 to N.fact ( ) with an argument of 1 (or) 0, the ... Read More
