A program to convert centigrade to fahrenheit and vice_versa
#include<stdio.h>
void main() {
float c,f,ic,fi; printf(“Enter centigrade : “);
scanf(“%f”,&c); f=1.8*c +32;
printf(“\n\nFahrenheit equivalent : %f\n\nEnter fahrenheit : “,f);
scanf(“%f”,&fi); ic=(fi-32)/1.8;
printf(“\nCentigrade equivalent : %f”,ic);
}
A program to find simple interest
#include<stdio>
void main{
float p,r,t,si,ci,amnt; int n;
printf(“Enter >> Principle, Rate, Time\n\n”);
scanf(“%f%f%f%d”,&p,&r,&t,&n);
si = (p*t*r)/100; printf(“\n\nSimple interest: %f”,si); }
#include<stdio.h> //Program header file, contains input output headers
void main() // main function
{ // start brace , program starts here
printf(“Hllo World!!”); // statement to print a line
} // end program
