Question

我正在尝试在C上编译它，但我无法看到哪里出错。

#include <stdio.h>

int verifica_quatro (int N, int M)
{   

    if  (M==N) 
        return 1;

    else 
        return -1;

}

int verifica_tres (int N, int M)
{

    if  (M==N) 
        return 1;

    else 
        return -1;

}

int verifica_dois (int N, int M)
{

    if  (M==N) 

        return 1;

    else 
        return -1;

}

int verifica_grupo (int N, int M)
{

    if (M == 0)
        M= 100;

    if (N == 0)
        N= 100;

    N= (N-1)/4;
    M= (M-1)/4;

    if (N == M)
        return 1;
    else
        return -1;

}

int main(void)
{
    int V, N, M, r;

    int valor = -1;

    int cont = 4;

    scanf("%d %d %d", &V, &N, &M);

    while !(M==0 && N==0 && V==0) {

        while (M>=10000) {
            M= M/10;
        }

        while (N>=10000) {
            N= N/10;
        }

    while (cont>0 && valor<0){

    if (cont == 4){
        r = verifica_quatro(N,M);
        valor = V*2500*r;

    }else if(cont == 3){
        N = N/10;
        M = M/10;
        r = verifica_tres(N,M);
        valor = V*510*r;
    }else if(cont == 2){
        N = N/100;
        M = M/100;
        r = verifica_dois(N,M);
        valor = V*77*r;
    }else if(cont == 1){
        N = N/100;
        M = M/100;
        r = verifica_grupo(N,M);
        valor = V*34*r;
    }

    cont--;

    }


      }

    if (valor<0)
        valor = 0;

    printf ("%d\n", valor);
      printf ("Digite M, N e V");
      scanf ("%d %d %d", &M, &N, &V);


    }

    return 0;
}

Answer 1

这是您成功编译的代码。

N=1000

在你的外部while循环中你写

while！（M == 0＆amp;＆amp; N == 0＆amp;＆amp; V == 0）

它应该是语法错误

while（！（M == 0＆amp;＆amp; N == 0＆amp;＆amp; V == 0））

#include <stdio.h> int verifica_quatro (int N, int M) { if (M==N) return 1; else return -1; } int verifica_tres (int N, int M) { if (M==N) return 1; else return -1; } int verifica_dois (int N, int M) { if (M==N) return 1; else return -1; } int verifica_grupo (int N, int M) { if (M == 0) M= 100; if (N == 0) N= 100; N= (N-1)/4; M= (M-1)/4; if (N == M) return 1; else return -1; } int main(void) { int V, N, M, r; int valor = -1; int cont = 4; scanf("%d %d %d", &V, &N, &M); while (!(M==0 && N==0 && V==0)) //Here a problem with () { while (M>=10000) { M= M/10; } while (N>=10000) { N= N/10; } while (cont>0 && valor<0) { if (cont == 4) { r = verifica_quatro(N,M); valor = V*2500*r; } else if(cont == 3) { N = N/10; M = M/10; r = verifica_tres(N,M); valor = V*510*r; } else if(cont == 2) { N = N/100; M = M/100; r = verifica_dois(N,M); valor = V*77*r; } else if(cont == 1) { N = N/100; M = M/100; r = verifica_grupo(N,M); valor = V*34*r; } cont--; } } if (valor<0) valor = 0; printf ("%d\n", valor); printf ("Digite M, N e V"); scanf ("%d %d %d", &M, &N, &V); //} This should be deleted return 0; }之前的大括号是额外的，它应该被删除。

Answer 2

中缺少一组括号

while !(M==0 && N==0 && V==0)

以这种方式修复：

while (!(M==0 && N==0 && V==0))

或者更令人困惑的是：

while (M|N|V)

另外：缩进你的代码，每个级别有4个空格，没有TABS！

Answer 3

这两行最后没有任何功能。加上chqrlie说的......

return 0;
}

预期的身份证明或＆＃39;（＆＃39;返回0之前？
