Basic C Programs on Control Statements, Looping, and Recursion

Easy C Programming Questions for Beginners

  1. Character Analysis: Determine if a character is a vowel or consonant, alphabet or not, or if it’s an uppercase, lowercase, or special character.
  2. Number Analysis: Check if a number is positive or negative, even or odd, or if it is prime, perfect, or strong.
  3. Arithmetic Operations: Calculate the area of a circle, find LCM/GCD of two numbers, and determine the greatest number among two or three values.
  4. Factorial and Fibonacci: Compute the factorial of a number or generate Fibonacci series up to a given term.
  5. Miscellaneous Problems: Reverse a given number, check for leap years, or find the sum of N natural numbers.

Medium-Level C Programming Questions

  1. Prime Numbers in a Range: Identify prime numbers within a specified range.
  2. Binary and Decimal Conversions: Convert between binary, decimal, octal, and hexadecimal formats.
  3. String Manipulation: Write programs to remove vowels from a string or check if two strings are anagrams.
  4. Pattern Printing: Print various patterns such as pyramid, diamond, and Floyd’s triangle.

C Programming on Strings: Core Concepts

Strings are an essential part of programming, and practicing string operations will help you build a strong foundation.
  1. String Operations:
    • Count the number of vowels in a string
    • Toggle each character of a string
    • Check if a string is a palindrome
    • Sort a string in alphabetical order
  2. String Manipulation:
    • Remove spaces or characters from a string
    • Replace substrings
    • Check for common subsequences in two strings

Arrays: Handling Data Efficiently in C

Arrays form the backbone of data management in C programming. Here are key problems to solve:

1-D Arrays:

  • Basic Operations: Insert, delete, and search elements in an array.
  • Element Analysis: Find the smallest/largest element, the second smallest element, or calculate the sum of positive square elements.
  • Array Sorting: Sort the elements in ascending or descending order.
  • Frequency Counting: Count the frequency of each element and find distinct or non-repeating elements.

2-D Arrays:

  • Matrix Operations: Perform addition, subtraction, and multiplication on matrices.
  • Special Matrix Operations: Check if a matrix is upper or lower triangular, or find the sum of boundary elements.
  • Matrix Rotation: Rotate matrices by 90 degrees in clockwise or anticlockwise direction.
 

Advanced C Programming Topics: Optimization and Complex Algorithms

As you progress, focus on these more complex problems that test your logic and optimization skills:
  • Knapsack Problem: Solve the 0/1 knapsack problem using dynamic programming.
  • Array Rotation: Implement various algorithms to rotate arrays, such as the juggling algorithm or block swap technique.
  • Equilibrium Index: Find the index where the sum of elements on both sides of an array are equal.

Conclusion: Take Your C Programming Skills to the Next Level

Practicing these C programming problems will prepare you for coding assessments and technical interviews. The more you practice, the better you’ll become at solving problems efficiently and optimizing your solutions.Click Here to know more our program: Must Solve C Programming Questions
