Learn to find the second biggest number by reading ten or more inputs in a loop, updating two trackers (big and s_big) to handle duplicates and reveal the result.

Identify and print perfect numbers below 100 by using an outer loop to generate candidates and an inner loop to sum their divisors, printing when the sum equals the number.

Generate and print strong numbers below 1000 by summing factorials of digits using nested loops, extracting digits, and comparing to the original number.

Read a name and a 12-digit number, validate the Aadhaar number using long long arithmetic by counting digits, and confirm registration with a congratulatory message.

Print number patterns by treating them as a matrix and using nested for loops with i and j to form sequences like 112123123412345 and 1223334445555.

Read a user-defined array of n elements, compute the total and the average, and validate input 1–100 before processing.

Fill a ten-element array with prime numbers starting at three, using nested loops to test primality by dividing from two to number-1 and store and display each prime.

Copy all elements from one array to another using a for loop, explaining why array assignment fails and guiding you to copy each element manually in C.

Explore binary search on a sorted array, using lower and upper bounds and midpoints to locate an element efficiently, with a practical C demonstration.

Learn to find minimum and maximum values in an array with a simple two-variable approach, initializing from the first element and updating in a loop.

Learn to count the frequency of each array element using a frequency array and nested loops, initializing counts to minus one and marking visited indices.

Learn to print the upper and lower triangles of a 5x5 matrix in C using i and j diagonal conditions, with the original array shown for reference.

Learn to convert an input string to proper case by capitalizing the first letter of each word and lowering the rest, using gets and ASCII tricks in Code Blocks IDE.

Demonstrates a simple password encryption by shifting each alphabet letter to its next character, preserving digits and special characters, with wrap from z to a and Z to A.

Learn to build a C program that checks palindrome strings by calculating string length, comparing first and last characters with a for loop, and reporting whether input is a palindrome.

Learn in this hands-on lab to compute the length of a string without white spaces in C by iterating to the null terminator and counting non-space characters.

Develop a C program that validates password length, counts uppercase, lowercase, digits, and special characters, and outputs strength levels from weak to very strong.

Learn to check palindrome strings in C by using strcpy to copy the input to a temp variable, strrev to reverse it, and strcmp to compare with the original.

Learn to read three subject marks and compute total and average using two separate functions in C: calc total and calc average, with input, output, and formatting.

Practice converting prime-checking logic into a function in C by building a prime_check that reads a number, tests divisibility from two to number-1, and returns 1 or 0.

Learn to count the digits of an input number in C using a digit count function, with global declarations and a loop that divides by ten.

Master swapping two numbers using a global declaration and a no-parameter swap function. Learn how global variables enable in-function changes and why this approach risks data security.
