函數_main中引用的未解析的外部符號_printf

Question

我是C編程的新手，正在編寫程序，它開始引發以下錯誤：

錯誤LNK2019無法解析的外部symbol_printf在function_main中引用

我正在使用C編譯器。

我的代碼如下所示：

#include <stdio.h>

int main(void)
{
    int EarthWeight;    // Weight on earth

    float Mercurypercent, Venuspercent,
    Marspercent, Jupiterpercent, Saturnpercent, Neptunepercent; // wieght percents

    float Mercurywieght, Venusweight, Marsweight, Jupiterweight, Saturnweight, Neptuneweight; // wieght outputs

    Mercurypercent = 0.378; // percent values of all the planets
    Venuspercent = 0.907;
    Marspercent = 0.377;
    Jupiterpercent = 2.36;
    Saturnpercent = 0.889;
    Neptunepercent = 1.12;  

    printf("what is the Weight of the person on earth? "); // Grabs the weight on earth
    scanf("%d", &EarthWeight);

    Mercurywieght = EarthWeight * Mercurypercent;
    Venusweight = EarthWeight * Venuspercent;
    Marsweight = EarthWeight * Marspercent;
    Jupiterweight = EarthWeight * Jupiterpercent;
    Saturnweight = EarthWeight * Saturnpercent;
    Neptuneweight = EarthWeight * Neptunepercent;

    Printf("Your Weight on Earth is: %d\n", EarthWeight);
    Printf("Your Weight on Mercury is: %f\n", Mercurywieght);
    Printf("Your Weight on Venus is: %f\n", Venusweight);
    Printf("Your Weight on Mars is: %f\n", Marsweight);
    Printf("Your Weight on Jupiter is: %f\n", Jupiterweight);
    Printf("Your Weight on Saturn is: %f\n", Saturnweight);
    Printf("Your Weight on Neptune is: %f\n", Neptuneweight);

    return 0;
}

C區分大小寫，您要調用Printf而不是printf 。

C也是對打字錯誤敏感的，並且您的問題和變量名中也包含一些內容，因此請注意...
