c - C中的BMI计算器，未声明的标识符

我正在尝试制作一个BMI计算器。我犯了多个“未声明的标识符”错误，即使我犯了这些错误？

#include <stdio.h>

int main(void)
{//main method

    //Ex 2.32
    printf("Ex 2.32: Body Mass Index Calculator\n\n");

    int weightInPounds;
    int heightInInches;
    int bmi;

    //displays title
    printf("Body Mass Index Calculator\n");

    //user input for weight
    printf("Please input your weight in pounds:\n");
    scanf("%d", &weightInPounds);

    //user input for height
    printf("Please input your height in inches:\n");
    scanf("%d", &heightInInches);

    //caluclate BMI
    bmi = (weightInPounds * 703) / (heightInInches*heightInInches);
    printf("\n");

    //display BMI categories
    printf("BMI Values\n");
    printf("Underweight: less than 18.5\n");
    printf("Normal: between 18.5 and 24.9\n");
    printf("Overweight: between 25 and 29.9\n");
    printf("Obese: 30 or greater\n\n");

    //display user BMI
    printf("Your BMI is: %d", &bmi);
    //end Ex 2.32

}//end main function

最佳答案

我测试了您的代码，效果很好！代码中有错误，例如：

printf("Your BMI is: %d", &bmi);

您只需要像这样打印它：

printf("Your BMI is: %d", bmi);
