计算电阻值的色带并输出

Question

I'm trying to develop a C program that calculates the resistor values by inputting the colour bands marked on the resistor.

忽略电阻公差这是我的代码 输出必须类似于 Calculating the resistor value with its color bands as input

我下面的代码没有给我想要的东西。我希望它能够循环返回 y 和 no。输出必须分开 {3}{3}

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <ctype.h>

int bandChoice;

char colorOne[10];

char colorTwo[10];
char colorThree[10];

float codeOne;

float codeTwo;

float codeThree;

float x;

void colorCodes();
void multiplier();
void color_code(char codeOne);


int main(void)

{  printf("Enter the colors of the resistor three bands, beginning with the band nearest the end. Type the colors in lowercase letters only, NO CAPS\n");
   puts(" ");

  printf("Band 1 = >");

  scanf("%s",colorOne);

  puts(" ");

  printf("Band 2 = >");

  scanf("%s",colorTwo);

  puts(" ");

  printf("Band 3 = >");

  scanf("%s",colorThree);
  puts(" ");


  printf("%f %f %f\n",colorOne,colorTwo,colorThree);

  x=(codeOne*10)+codeTwo;

  printf("Resistance value  %d");

 } 




void color_code(char codeOne )
{

  if(strcmp(colorOne, "black") == 0)
  {
    codeOne=0;
      } 
else
  if(strcmp(colorOne, "brown") == 0)
  {
    codeOne=1;
      } 
else
  if(strcmp(colorOne, "red") == 0)
  {
    codeOne=2;
      }

  if (strcmp(colorOne, "orange") == 0)
  {
    codeOne=3;

  }

}
void multiplier()
{
    if(strcmp(colorThree, "black") == 0)
    {
        codeThree=1;
    } else

    if(strcmp(colorThree, "brown") == 0)
    {
        codeThree=10;
    } else

    if(strcmp(colorThree, "red") == 0)
    {
        codeThree=pow(10.0,2);
    } else
    if (strcmp(colorThree, "orange") == 0)
    {
        codeThree=pow(10.0,3);
    } else
    if (strcmp(colorThree, "yellow") == 0)
    {

      }

如果有人能提供帮助，我将不胜感激

1. 您的color_code 函数设计不当。您应该将颜色字符串作为输入并返回代码字符串。

.

char color_code(char *colorOne )
{
  char codeOne;
  if(strcmp(colorOne, "black") == 0)
  {
    codeOne=0;
  } 
  // and so on for other colors

  // at the end
  return codeOne;
}

1. 主要是，您需要在 scanf 之后调用此 color_code 函数

.

codeOne = color_code(colorOne);

1. 您还需要对其他三个函数重复此操作。

2. 变量 colorOne colorTwo colorthree codeOne codeTwo codeThree 可以在 main 本地，而不是全局。
