A file represents a sequence of bytes and these file’s is used to store information. There are various different operations that we can be performed on a file are: Creation of a new file (fopen with attributes as “a” or “a+” or “w” or “w++”) Opening an existing file (fopen) Reading from file (fscanf or … Read more
In a C programming, we can also perform arithmetic operations with pointer. There are four arithmetic operators that can be performed with pointers: Increment (++) Decrement ( — ) Addition ( + ) Subtraction ( – ) For a simple variable int a=3;a++; //print 4Increment integer value by one. Pointer is a variable which can … Read more
In a programming often a situation may comes where we want to execute the set of code again and again. Loop has a ability to repeat set of statement until a condition to be satisfied or a particular number of times. There are following types of loop in C language: In a C programming language … Read more
In C programming, both structures (structs) and unions are used to define custom data types that can hold multiple variables of different data types. However, they have distinct differences in terms of how they allocate memory and how they store data: 1. Memory Allocation: 2. Memory Usage: 3. Accessing Data: 4. Use Cases: Aspect Structure … Read more
C is computer programming language developed in 1972 by Dennis M. Ritchie. C programming language developed in Bell Laboratories to develop the UNIX operating system. C is a high-level language which can be easily read and written by any one. C is a case-sensitive programming language. Thus, “HELLO” and “Hello” two different identifiers in C.
1. What is data type in C Data type specifies what type of data a variable can hold. There are four category of data type in C language. They are as follows: Types Data Types Basic (Primitive) data types int, char, float, double Enumeration data type Enum Derived data type pointer, array, structure, union Void … Read more
Here We learn Array in C how to Declare Initialize and access array and operations on array. Array is a data structure that can store elements of the same type. Array is a collection of similar type elements It stores the elements in a contiguous memory locations. 1 Why Array Required? Array is used to … Read more
For loop in C programming is a statement to repeat the set of statements until a condition to be satisfied. Syntax of for loop statement: for(initialization; conditionCheck; updation ) { statement 1; statement 2; ————– } “for-statement” has a initialization , condition and iteration (increment/ decrement) part separated by semicolon. Initialization : This phase allows … Read more
like a while statement, “ do while statement” repeats a set of statements if condition is true. If condition is false the flow of control do not enter inside the do-while loop. “do-while” first execute the body of loop than tests the condition. Means even if the condition if false do-while executes at least ones. … Read more
“while loop” repeats a set of statements if condition is true. If condition is false the flow of control do not enter inside of while loop. It first tests the condition then execute the body of loop. Syntax of a while statement− while(condition) { Statement1; Statement2; —- —- Increment/Decrement; } Example: Write a program to print … Read more
