c - 我在 C 程序中没有得到正确的输出？

Question

我正在为 C 程序使用 Dev-c++ 和 Code::Blocks IDE。我想从用户循环最多 10 次。但我没有得到正确的输出。我第一次从第二次获得正确的输出后我没有得到正确的输出。

#include<stdio.h>

main() {
char g;
int yos,qual,sal,a = 1;
printf("\nEnter M for Male and F for Female");
printf("\nEnter 0 for Graduate and 1 for Post-Graduate");

while(a<=10) {
    printf("\n\n\nEnter  gender, year of service , qualification : ");
    scanf("%c%d%d",&g,&yos,&qual);
    if(g=='M' && yos>=10 && qual==1)
    sal = 15000;
    else if((g=='M' && yos>=10 && qual==0) || (g=='M' && yos<10 && qual==1))
        sal = 10000;
    else if(g=='M' && yos<10 && qual==0)
        sal = 7000;
    else if(g=='F' && yos>=10 && qual==1)
        sal = 12000;
    else if(g=='F' && yos>=10 && qual==0)
        sal = 9000;
    else if(g=='F' && yos<10 && qual==1)
        sal = 10000;
    else if(g=='F' && yos<10 && qual==0)
        sal = 6000;
    printf("\nSalary of the employee is : %d",sal);
        a++;
    }

}

Answer 1

两件事。在 scanf() 中的 %c 之前放置一个 space 将吃掉它之前的所有空格，并检查 返回的正确输入数code>scanf() 将防止愚蠢的输出。我输入了第一组 newline 分隔符，第二组使用 space 分隔符。

#include <stdio.h>

int main()
{
    char g;
    int yos, qual;

    printf("\nEnter char, int, int: ");
    if (3 != scanf(" %c%d%d", &g, &yos, &qual))
        printf ("Error\n");
    else
        printf("You entered: %c %d %d\n", g, yos, qual);

    printf("\nEnter char, int, int: ");
    if (3 != scanf(" %c%d%d", &g, &yos, &qual))
        printf ("Error\n");
    else
        printf("You entered: %c %d %d\n", g, yos, qual);

    return 0;
}

程序输入/输出

Enter char, int, int: a
1
2
You entered: a 1 2

Enter char, int, int: b 6 7
You entered: b 6 7
