Let’s take an example of array declaration on C programming.   int z[25] It reserves memory space for 25 integer numbers, Sometimes, the problem arises with this declaration. If the user needs to work on more than 25 values the allocated memory will not be sufficient. Besides, if the user needs to work on less […]

Same way as other variables, we have to declare pointers before we use them. Pointer declarations are the same as other declarations. When pointers are declared, the keyword for declaration is int, char, etc. declares the type of the pointer variable. The pointer type specifies the type of the variable to which the pointer points. For […]

A pointer is a variable that stores the address of another variable. Pointers are much used in C, partly because they are sometimes the only way to express a computation, and partly because they usually lead to more compact and efficient code than that can be obtained in other ways. Pointers and arrays are closely […]

The array is the collection of similar data items that can be represented by a single variable name. The individual data items in an array are called elements. A data item is stored in memory in one or more adjacent storage locations depending upon its type. An array is also known as a series of […]

Recursive can be regarded as the ability of function defining an object in terms of a simpler case of itself. It is a process by which a function calls itself repeatedly until some specific condition has been satisfied. The problem must be written in recursive form. The problem statement must include a stopping condition. A […]

C program consists of one or more functions along with function main(). Functions are known as modules this will make a program to easy. In Every program the main() function should be placed, in every program library function like printf(). sqrt(). pow() etc. C Function easy to define and use. The function is one of […]

For Loop The for loop is one of the powerful loop and flexible loop which provides a more concise loop control structure. It is a pre-test or entry control loop similar to while loop. A program can also use a while loop instead of for loop. If loops are nested then the for loop is […]
