我在获取二维数组元素的最小值、最大值和平均值时遇到问题。
我有一个包含学生和成绩的二维数组。
我正在用 rand 生成成绩。例如,当我输入 2,2 时,它会将我打印出来
Courses : 01 02 Average Min Max
ID
01 8 50 29
02 74 59 29
,我的平均函数取第一个平均值,而不取其他平均值。
这是我的代码;
int A[30][30];
int findAverage(int noOfStudents ,int noOfGrades ){
float sum,average;
for (int i = 0 ; i < noOfGrades ; i++) {
for (int j = 0; j<noOfStudents; j++) {
sum += A[i][j];
}
average = sum / noOfGrades;
// cout << " " << format(average);
sum = 0;
return format(average);
}
以及我如何使用它
int main() {
int noOfCourses , noOfStudents;
cin >> noOfCourses >> noOfStudents;
cout << "Courses : " ;
for (int i = 0; i < noOfCourses; i++) {
if (i+1 >= 10) {
cout << i+1 << " ";
}else{
cout <<"0" << i+1 << " ";
}
}
cout << "Average Min Max";
for(int i=0; i<noOfStudents; i++) { //This loops on the rows.
for(int j=0; j<noOfCourses; j++) { //This loops on the columns
A[i][j] = genGrade();
}
}
cout << "\n ID " << endl;
for(int i=0; i<noOfStudents; i++) { //This loops on the rows.
if (i+1 >= 10) {
cout <<" " << i+1 << " ";
}else{
cout <<" 0" << i+1 << " ";
}
//cout <<" 0" << i+1 << " ";
for(int j=0; j<noOfCourses; j++) { //This loops on the columns
if (A[i][j] >= 10 && A[i][j] <=99) {
cout <<" " << A[i][j] << " ";
}
if(A[i][j] < 10) {
cout <<" " << A[i][j] << " ";
}
if (A[i][j] == 100) {
cout << A[i][j] << " ";
}
}
cout <<" "<<findAverage(noOfStudents,noOfCourses);
cout << endl;
}
}
我究竟做错了什么 ?另外我怎样才能得到每个数组的最小值,最大值?
