Basic C Programs

1) C Program to Print Hello World

Code:
#include <stdio.h> int main() { printf("\n Hello World"); return 0; }
Output:

2) Program to add Two numbers

Code:
#include <stdio.h> int main() { int number1, number2, sum; printf(" Enter two integer values \n "); scanf("%d %d", &number1, &number2); sum = number1 + number2; printf(" Sum of the two integer values is %d", sum); return 0; }
Output:

3) C Program to Calculate Compound Interest

Code:
#include <stdio.h> #include <math.h> int main() { float PAmount, ROI, Time_Period, CIFuture, CI; printf("\nPlease enter the Principal Amount : \n"); scanf("%f", &PAmount); printf("Please Enter Rate Of Interest : \n"); scanf("%f", &ROI); printf("Please Enter the Time Period in Years : \n"); scanf("%f", &Time_Period); CIFuture = PAmount * (pow(( 1 + ROI/100), Time_Period)); CI = CIFuture - PAmount; printf("\nFuture Compound Interest for Principal Amount %.2f is = %.2f", PAmount, CIFuture); printf("\nCompound Interest for Principal Amount %.2f is = %.2f", PAmount, CI); return 0; }
Output:

4) C Program to Check Odd or Even

Code:
#include <stdio.h> int main() { int number; printf(" Enter an int value to check Even or Odd \n"); scanf("%d", &number); if ( number%2 == 0 ) //Check whether remainder is 0 or not printf("Given number %d is EVEN NUMBER \n", number); else printf("Given number %d is ODD NUMBER \n", number); return 0; }
Output:

5) C Program to Print Multiplication Table using For Loop

Code:
#include <stdio.h> int main() { int i, j; printf("\n Multiplication Table of 8 and 9 are: \n"); for (i = 8; i < 10; i++) { for (j = 1; j <= 10; j++) { printf("%d * %d = %d\n",i ,j, i*j); } printf("\n ==========\n"); } return 0; }
Output:
