Basic Programming
Input - Output - Variables - Constants
Print text Count number of words, lines and chracters Read 2 numbers from user - computes sum Size, addr of variable of type int , float, char Declaration , initialization, print constant vari Reference variablesBitwise Operators
Bitwise operator OR ( | ) Bitwise Operator AND (&) Bitwise Operator XOR ( ^ ) Bitwise Operator Left Shift ( << ) Bitwise Operator Right Shift ( >> )Conditional Statements
Reads marks - test of 100 marks - print pass Reads number and prints even or odd number Read, compute, display grade using switch case Read marks, compute grade using if else Compute, display result - ternary operator ( ? : ) Read integers, operator, evaluate - switch caseLoops - Continue/Break Statement
Prints 10 integers using for loop Display sum of ten integers using for loop Print odd numbers from 0 to 50 using for Loop Compute, displays num factorial using for loop Histogram using nested for loop Print a diamond using nested for loop Square of ten integers using for loop Print 20 integers using while loop Print 20 int in reverse order using while loop Odd num, even num, divisible by 5 b/w 0 to 50 Display num digits in reverse order - while loop Display num in reverse order - do while loop Display factorial using do-while loop Even num - 0 to 50 - while, do-while, for loop Use of the break statement Use of the continue statementFunctions
Use of parameterless function Largest int among 3 - function with no return type Largest int among 3 - function with return type Use of call-by-value method in functions Use of call-by-refrence method in functions Use of inline functions Use of default argument function Use of function overloading Find distance b/w 2 points - function overloading Example of function overloading Example if built-in function Compute nCr Built int functions strcomp, strcmpi, stricmp Storage class Auto, Static with global variableArrays
Find largest element of an array Initialize array by even numbers display sum Reverse the content of an integer array Histogram using array Print an array using function definition Read marks of students display total marks, status Whole array, single array elmt as parameter to fn Bubble sorting of arrays Search element in an array - Linear search Search element in an array - Binary search Read 2D array, display it row by row and sumPointers - Strings
Use of operator * and & Supplying of values to pointer variables Adding values to the contents of variables Use of pointer to pointers Functions returning pointers Operations performed on pointers 2D array of int using pointers 2D array of char (string) using pointers Srray before and after adding 5 to its contents Use of call-by-reference method using pointers Sum, smallest, largest element an array pointers Features of array of char known as string Example of constant pointers to non-constant dataRecursion
Computes and displays the factorial of number Computes n_th term of the fibonacci series Towers of Hanoi ProblemGeneral Programs
Find Book in the list of Books Year is a leap year or not Swap two variables using header file swap.h Find day of a week of a given date using arrays Convert decimal into binary, octal, pental code Covert given decimal into Roman Code Covert given Decimal into English Code Add two integers without using + operator Factorial of first five elements of the fibonacci Add two integers of any length Non-Linear function in one variable and evaluate
