C program to convert upper case to lower and vice versa by using string concepts
Converting uppercase letters to lowercase and lowercase letters to uppercase is commonly known as case toggling. In C programming, we can achieve this using ASCII values or built-in character functions. Syntax // Manual approach using ASCII values if (ch >= 'a' && ch = 'A' && ch = 'a' && string[i] = 'A' && string[i]
Read MoreC program to verify if the numbers are abundant(friendly) or not?
In C programming, abundant numbers (also called friendly numbers) are special numbers where the sum of their proper divisors equals the number itself. Two numbers form an abundant pair if both numbers are abundant individually. Syntax // Find sum of proper divisors for(i = 1; i < number; i++) { if(number % i == 0) { sum = sum + i; } } // Check if abundant if(sum == number) { // Number is abundant } ...
Read MoreExplain Squeeze Function C language
The squeeze() function in C is a user-defined function that removes all characters from the first string that are present in the second string. This function is particularly useful for filtering characters based on a reference string. Syntax void squeeze(char string1[], char string2[]); Parameters string1[] − The source string from which characters will be removed string2[] − The reference string containing characters to be removed from string1 How It Works The squeeze function works by scanning each character in the first string and checking if it exists in the second ...
Read MoreWrite 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 − ...
