Question

Please write a code in C that will allow the user to choose to calculate voltage, resistance or current. Then the program will prompt the user to enter the necessary values and output the result.

Answer 1

code:

#include <stdio.h>
int main()
{
    double i,v,r;
   int ch;
    printf("1.Current\n2.Resistance\n3.Voltage\nWhat do you want to calculate(enter 1 or 2 or 3)?:");
    scanf("%d",&ch);
    if(ch==1)
    {
        printf("Enter resistance:");
        scanf("%f",&r);
        printf("Enter voltage:");
        scanf("%f",&v);
        printf("Current= %.2f",v/r);
   }
   if(ch==2)
    {
        printf("Enter current:");
        scanf("%f",&i);
        printf("Enter voltage:");
        scanf("%d",&v);
        printf("Resistance= %.2f",v/i);
   }
   if(ch==3)
    {
        printf("Enter resistance:");
        scanf("%f",&r);
        printf("Enter current:");
        scanf("%f",&i);
        printf("Current= %.2f",i*r);
   }
return 0;
}

Note: Due to some technical issues I fail to upload screenshots of output. But I can assure you best output for the above code
