Convert vowels from upper to lower or lower to upper using C program
In C programming, we can convert vowels in a string from uppercase to lowercase or lowercase to uppercase using character manipulation functions. This involves checking each character to identify vowels and then applying the appropriate case conversion. Syntax #include int toupper(int c); // Converts to uppercase int tolower(int c); // Converts to lowercase Method 1: Convert Lowercase Vowels to Uppercase This approach converts all lowercase vowels (a, e, i, o, u) to their uppercase equivalents while keeping other characters unchanged − #include #include ...
Read MoreC Program to find the given number is strong or not
A strong number is a number where the sum of the factorial of its digits equals the number itself. For example, 145 is a strong number because 1! + 4! + 5! = 1 + 24 + 120 = 145. Syntax int factorial(int n); int isStrongNumber(int num); Understanding Strong Numbers Let's examine some examples to understand the concept better − 145 = 1! + 4! + 5! = 1 + 24 + 120 = 145 (Strong number) 123 = 1! + 2! + ...
Read MoreC Program to find two's complement for a given number
The two's complement is a mathematical operation used to represent negative numbers in binary form. It can be calculated using two methods − Method 1 − Convert the given binary number into one's complement and then add 1. Method 2 − Starting from the rightmost bit, copy all bits until the first '1' (including it), then complement all remaining bits. Syntax // One's complement: flip all bits // Two's complement: one's complement + 1 How Two's Complement Works The two's complement process involves these steps − Find the one's ...
Read MoreWhat is enumerated data type in C language?
An enumerated data type in C is a user-defined data type that allows programmers to create variables with a restricted set of named values. It provides a way to assign names to integer constants, making code more readable and maintainable. The keyword is enum. Syntax enum tagname { identifier1, identifier2, ..., identifier_n }; Basic Example Here's how to declare an enumeration for days of the week − enum week { mon, tue, wed, thu, fri, sat, sun }; By default, identifier ...
Read MoreC Program to delete the duplicate elements in an array
In C programming, removing duplicate elements from an array means creating a new array that contains only unique elements. This is a common array manipulation task that helps eliminate redundancy in data. Syntax for(i = 0; i < size; i++) { for(j = i + 1; j < size; j++) { if(arr[i] == arr[j]) { // Shift elements left to remove duplicate ...
Read MoreC Program to count trailing and leading zeros in a binary number
In C programming, counting trailing and leading zeros in a binary representation of a number is a common bit manipulation task. Trailing zeros are the consecutive zeros from the least significant bit (LSB) until the first set bit, while leading zeros are the consecutive zeros from the most significant bit (MSB) until the first set bit. Syntax /* For trailing zeros */ int countTrailingZeros(int number); /* For leading zeros */ int countLeadingZeros(int number); Trailing Zeros Trailing zeros are the zeros that appear after the rightmost set bit (1) when counting from ...
Read MoreC program to rotate the bits for a given number
Bit rotation is a fundamental bitwise operation where bits in a number are shifted circularly. In left rotation, bits move left and the leftmost bit wraps to the rightmost position. In right rotation, bits move right and the rightmost bit wraps to the leftmost position. Syntax // Left rotation int leftRotate(int num, int rotations); // Right rotation int rightRotate(int num, int rotations); Key Concepts Left rotation: Bits are shifted left, MSB wraps to LSB position Right rotation: Bits are shifted right, LSB wraps to MSB position Circular shift: No bits ...
Read MoreC Program to check whether the triangle is equilateral, isosceles or scalene
A triangle consists of three sides and three angles. Based on the relationship between the three sides, triangles can be classified into three types − Equilateral triangle: All three sides are equal. Isosceles triangle: Any two sides are equal. Scalene triangle: No sides are equal. Syntax if (side1 == side2 && side2 == side3) { // Equilateral triangle } else if (side1 == side2 || side2 == side3 || side1 == side3) { // Isosceles triangle } else { // Scalene triangle ...
Read MoreC Program to calculate the difference between two time periods
In C programming, calculating the difference between two time periods is a common problem that involves handling the borrowing mechanism similar to subtraction in arithmetic. This program takes two time periods as input and computes their difference in hours, minutes, and seconds format. Syntax struct time { int hrs; int min; int sec; }; void diff_between_time(struct time start, struct time stop, struct time *diff); Algorithm The logic to find the difference between start and stop time involves borrowing when the stop ...
Read MoreC program to find maximum occurrence of character in a string
In C programming, finding the character with maximum occurrence in a string involves counting the frequency of each character and determining which appears most often. This is useful for text analysis and character statistics. Syntax int frequency[ASCII_SIZE]; while(string[i] != '\0') { frequency[(int)string[i]]++; i++; } Algorithm The algorithm to find maximum occurrence follows these steps − Initialize a frequency array to count occurrences of each ASCII character Traverse the string and increment frequency count for each character Find the character with maximum frequency count ...
