#include <stdio.h>

int main()
{
    int a, n;
    float p;

    printf("Please enter article characteristics.\n");
    printf("Article Number: ");
    scanf_s("%d", &a);
    printf("Number of pieces: ");
    scanf_s("%d", &n);
    printf("Price per piece: ");
    scanf_s("%.1f", &p);

    printf("\n\tArticle Number\tQuantity\tPrice Per Piece\n");
    printf("\t     %d\t\t%d\t     %.1f Dollar", a, n, p);
    return 0;
}

当我运行代码时,我能够输入第一部分,但一旦我输入第二部分,我就会得到错误。即使我删除了第二部分,当我输入第一个输入时,我也会得到错误。

用户输入可能因人而异,因此最好使用scanf(“%f”,&p)而不是scanf(“%.1f”,&p),但在显示值或执行其他操作时,您可以根据需要更改小数点后一位(.1f)或两位(.2f)。下面是正确的代码:

#include <stdio.h>
int main()
{
    int a, n;
    float p;
    printf("Please enter article characteristics.\n");
    printf("Article Number: ");
    scanf("%d", &a);
    printf("Number of pieces: ");
    scanf("%d", &n);
    printf("Price per piece: ");
    scanf("%f", &p);
  
    printf("\n\tArticle Number\tQuantity\tPrice Per Piece\n");
    printf("\t     %d\t\t%d\t     %.1f Dollar", a, n, p);
    return 0;
}
