我有一个程序，其中有一个包含 10 个struct变量的数组，称为students. 在students我有一个用 20 个元素char调用的数组变量。testAnswers我要做的是将这十名学生testAnswers与一个名为20 个元素的char数组变量进行比较。answers基本上，变量answers是学生的答题卡testAnswers。答案都是真/假。这是我到目前为止所拥有的：
注：numStu是 10 和numAns20。
void checkAnswers(char answers[], student students[]){
for (int i = 0 ; i < numStu ; i++){
for (int d = 0 ; d < numAns ; d++){
if (students[i].testAnswers[d] == ' '){
students[i].score += 1 ; //if the student did not answer the question add 1 which will be substracted once if loop sees it is not correct resulting in the student losing 0 points.
}
if (strcmp(answers[d],students[i].testAnswers[d]) == 0){
students[i].score +=2 ;//if the student answer is correct add 2 points to score
}
if (strcmp(answers[d],students[i].testAnswers[d]) != 0){
students[i].score -= 1 ; //if the student answer is incorrect substrct 1 point
}
}//end inner for
}//end for outer
}//end checkAnswers
我继续收到的错误：
invalid conversion from char to const char
initializing argument 1 of `int strcmp(const char*, const char*)'
对于我使用strcmp. 我想知道是否有任何方法可以纠正这个错误，或者有什么更好的方法来比较这两个字符并为测试评分。
