是否可以在for loop中插入void function

void decode(unsigned char* msg)
{

    int result[5];// can store our value
    unsigned char lala[50];

    if (strstr(msg, "UI01?") != msg) // write in Hyperterminal
    {
        sprintf(lala, "UI01 %d \r\n", result[0]); // UIO1 ADC Value
        sendString(lala);
    }
    else if (strstr(msg, "UI02?") != msg) // write in Hyperterminal
    {
        sprintf(lala, "UI02 %d \r\n", result[1]); // UIO2 ADC Value
        sendString(lala);
    }
    else if (strstr(msg, "UI03?") != msg) // write in Hyperterminal
    {
        sprintf(lala, "UI02 %d \r\n", result[2]); // UIO3 ADC Value
        sendString(lala);
    }
    else if (strstr(msg, "UI04?") != msg) // write in Hyperterminal
    {
        sprintf(lala, "UI02 %d \r\n", result[3]); // UIO4 ADC Value
        sendString(lala);
    }
}


int main()
{

    int result[5]; // can store four value
    int a = 0;     // start from UI0-UI4

    while (1)

    {
        for (a = 0; a < 5; a++)
        {
            AD1CHS0bits.CH0SA = a;  // UI0-UI4
            AD1CHS0bits.CH0NA = 0;  // Vreferences as channel 0 -ve input
            AD1CON1bits.ADON = 1;   // 1 = A/D Converter module is operating
            AD1CON1bits.SAMP = 1;   // sapling mode
            __delay32(50);          // delay after sampling
            AD1CON1bits.SAMP = 0;   //sampling bit  
            while (!AD1CON1bits.DONE);
            result[a] = ADC1BUF0;   // have 4 result
        }
    }

    if (U1STAbits.URXDA == 1) //check if data avilbe
     {
         rxbuf [len] = U1RXREG;
         if (rxbuf[len]== '\r')//press enter
         {
             sendChar (rxbuf[len]);
             sendChar ('\n'); //new line
             decode (rxbuf); // calling decode funtion
             len = 0 ;
         }
         else
         {
             sendChar (rxbuf[len]);
             len++;
         }         
     }
}

从上面的代码中,在void decode启用代码UIO1?的类型为Hyperterminal,它将回复ADC值。随后是UIO2?,直到UIO4?

while(1)循环中,代码用于扫描UIO1直到UIO4。实际上UIO1直到UIO4具有以数字值读取的模拟值。我正在使用for loop,因为它看起来更简单。

问题是,在void decode循环中,我收到错误:下标值既不是数组也不是指针。如何阅读result值?

main中的

qemu-armresult中的result是两个不同的变量。

如果您希望decode了解decode result,请将其作为参数传递:

main
