### Program to Convert String into Lowercase Using Library Function

C Determine and Print if the Value is Odd - C Using conditional statement (if-else) in an iteration (i.e. for loop). We shall initiate a for loop having some finite iterations and check every value of it. if conditional statements...

Program to Implement the RSA Algorithm - Encodes any message using 'RSA Algorithm'. Input is 'Case Sensitive' and works only for all characters. RSA is one of the first practicable 'public-key' cryptosystems and is widely used

C++ Compare Binary & Sequential Search - A 'function implementing' Binary search on a 'Sorted array'. Every time this function called, counted as a iteration of 'binary search'. So if value is "Less than Value" at start index more

C Program to calculate Area of a Polygon - Given the coordinates of the vertices of a convex polygon, calculate its area and perimeter. Subdivide it into triangles and calculate the area of each triangle with the

C++ Programs Use Above Below Primitive - Program to check whether two lines intersect to each other. The above-below primitive can be used to test whether a line intersects a line segment. It does iff one endpoint of segment

C++ Program to Find Factorial of Number - First think what is the factorial of a number? How 'mathematically' it can be calculated. If you got this info then it will be very easier to make a C++ code logic to find the "Factorial".

Program Finds Sum of Digits of a Number - Logic to find sum of digits of a given number in C programming. The main idea to find sum of digits can be divided in three steps. Extract last digit of the given number. Add extracted

C Program Convert Binary to Hexadecimal - C Language program takes a binary number as input and converts to hexadecimal. Take a binary number as input. And divide the binary number into groups of 4 bits. For each group
