Write a C program to display all datatypes ranges in tabular form
In C programming, data types define the type and range of values that can be stored in variables. This program displays all fundamental data types with their minimum and maximum ranges in a tabular format using the limits.h header file. Syntax #include #include // Use predefined constants like INT_MIN, INT_MAX, FLT_MIN, FLT_MAX Primary Data Types C supports four fundamental data types − Integer − Stores whole numbers (int, short, long) Character − Stores single characters (char) Floating-point − Stores decimal numbers (float) Double precision − Stores high-precision decimal numbers (double) ...
Read MoreWhat are the shift operations in C language?
Shift operations in C are bitwise operators that move bits of a number left or right. These operations are fundamental for bit manipulation and can be used for efficient multiplication and division by powers of 2. Syntax variable > n // Right shift by n positions ~variable // Bitwise complement (NOT operation) Left Shift Operation The left shift operator () moves bits to the right by specified positions. Each right shift by one position halves the value (for positive numbers). ...
Read MoreHow to count number of vowels and consonants in a string in C Language?
In C programming, counting vowels and consonants in a string is a common string manipulation task. We iterate through each character and check if it's a vowel (a, e, i, o, u) or consonant using conditional statements. Syntax // Check if character is vowel if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') vowels++; else if(isalpha(ch)) ...
Read MoreC program to print multiplication table by using for Loop
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. In this tutorial, we will learn how to print a multiplication table using a for loop in C. Syntax for (initialization; condition; increment/decrement) { // statements to be executed } Algorithm Given below is an algorithm to print multiplication table using for loop in C language − Step 1: Enter a number to print table at runtime. Step 2: Read that number from keyboard. Step 3: Using for loop print number*i 10 times. // for(i=1; i
Read MoreHow to write a simple calculator program using C language?
A calculator is a simple tool that helps us to calculate mathematical operations easily and quickly. A basic calculator can perform simple arithmetic operations like subtraction, addition, multiplication, and division. In C programming, we can create a calculator using switch-case statements to handle different operators and perform calculations based on user input. Syntax switch(operator) { case '+': result = num1 + num2; break; case '-': result = num1 - num2; break; case '*': result = num1 * num2; break; case ...
Read MoreWrite a C program to find out profit or loss in buying an article
In business transactions, calculating profit or loss is essential to determine the financial outcome. Profit occurs when the selling price exceeds the cost price, while loss occurs when the cost price is greater than the selling price. Syntax if (selling_price > cost_price) { profit = selling_price - cost_price; } else if (cost_price > selling_price) { loss = cost_price - selling_price; } else { // No profit, no loss } Formulas The formulas for calculating profit and loss are − Profit: ...
Read MoreHow to write the temperature conversion table by using function?
Temperature conversion is nothing but converting Fahrenheit temperature to Celsius or Celsius to Fahrenheit. In this programming, we are going to explain how to convert the Fahrenheit temperature to Celsius temperature and how to represent the same in the form of a table by using a function. Syntax // Function to convert Fahrenheit to Celsius float fahrenheitToCelsius(float fahrenheit); // Function to convert Celsius to Fahrenheit float celsiusToFahrenheit(float celsius); Example 1: Fahrenheit to Celsius Conversion Table Following is the C program for temperature conversion table from Fahrenheit to Celsius − ...
Read MoreExplain the variable declaration, initialization and assignment in C language
In C programming, variables are named storage locations in memory that hold data values. Unlike constants, variables can have their values modified during program execution. Before using any variable, it must be declared to inform the compiler about its data type and name. Syntax data_type variable_name; data_type variable_name = initial_value; data_type var1, var2, var3; Variable Declaration Variable declaration tells the compiler to reserve memory space for a variable with a specific data type. The syntax is − type variable_name; or for multiple variables of the same type − ...
Read MoreAccessing variables of Int and Float without initializing in C
When we declare variables in C without initializing them, their values are unpredictable. This article demonstrates what happens when we try to access uninitialized int and float variables and explains the underlying memory behavior. Syntax data_type variable_name; // Declaration without initialization Understanding Uninitialized Variables When a variable is declared but not initialized, the following occurs − Memory is allocated for the variable during declaration The memory location contains whatever data was previously stored there This results in garbage values − unpredictable leftover data from previous program executions The actual ...
Read MoreGiven an example of C pointer addition and subtraction
Pointer arithmetic is a fundamental concept in C programming that allows you to perform mathematical operations on pointer variables. Two important operations are pointer addition and subtraction, which help navigate through memory addresses. Syntax /* Pointer Addition */ new_address = current_address + n; /* Pointer Subtraction */ new_address = current_address - n; Where n is the number of elements to move, and the actual byte offset is calculated as: n * sizeof(data_type) C Pointer Addition Pointer addition involves adding an integer value to a pointer. The result is a new memory address ...
