“错误：在C编译时发生'\ 342'”，“stray'\ 200'”，“stray'\ 234'”错误？

Question

我明白这个问题之前已经被问过了，请不要把它钉在十字架上。我用NotePad ++来编写代码，当我试图编译它时（我使用cc lab7.c -o test1来编译它），我得到了一堆迷路的\ 342，stray \ 200，stray \ 234错误，正如所见下面。

这里是我的代码：

#include <stdio.h> 
#include <string.h> 


char inbase, dummy, outbase; 
char response; 
int inputNum; 
char bin [32]; 

int main(void) 
{ 


// perform for yes response 
while (response == 'y' || response == 'Y') 
{ 

    // prompt to read in char for base of input 
    printf("Enter a base to read in (b for binary, d for decimal,\n h for hexidecimal, or o for octal: "); 
    scanf("%c", &inbase); 

    // if binary is inbase 
    if (inbase == 'b' || inbase == 'B') 
    { 
     printf ("Enter a binary number to read: "); 
     scanf ("%c", &dummy); 
     scanf ("%s", bin); 
     inputNum = binary(bin); 
    } 

    // if inbase is anything else, read 
    else 
    { 
     printf ("Enter an integer to read: "); 
     scanf ("%c", &dummy); 
     scanf ("%i", &inputNum); 
    } 

    // output the number 

    printf ("Enter a base to output as: "); 
    scanf ("%c", &dummy); 
    scanf ("%c", &outbase); 

    // decimal output 
    if (outbase == 'd' || outbase == 'D') 
    { 
     printf("The integer %i in decimal is %d" inputNum, inputNum); 
    } 

    // hexidecimal output 
    if (outbase == 'h' || outbase == 'H') 
    { 
     printf("The integer %i in hexidecimal is %h" inputNum, inputNum); 
    } 

    // octal output 
    if (outbase == 'o' || outbase == 'O') 
    { 
     printf("The integer %i in octal is %o" inputNum, inputNum); 
    } 

    // check to see if user wants to run again 
    printf (“Do you want to …”); 
    scanf (“%c”, &dummy); 
    scanf (“%c”, &response); 
    scanf (“%c”, &dummy); 

} 

int binary(char* inString) 
{ 
    int sum=0; 
    int i; 

    for (i=0; i < strlen(inString); i++) 
    { 
     sum = sum * 2 + (inString[i] - 48); 
    } 

    return sum; 
} 

return 0; 

} 

// END OF CODE 

这里是错误消息我得到：

Answer 1

有几个问题与您的代码：

lab7.c:58:45: error: expected ‘)’ before ‘inputNum’ 
printf("The integer %i in decimal is %d" inputNum, inputNum); 
             ^

您在指定位置之前缺少一个逗号，并且在后面的几行相似的行中。

printf (“Do you want to …”); 
     ^   ^

在我指定的位置引号都是“智能引号”（“/”），不正常的引号。重新输入它们。

同样的问题适用于以下与“%c”有关的每个错误。
