我被困在一個問題上。我正在嘗試在此計劃任務中找到QUIZZES的平均值。這是我的代碼。 Bold中的代碼是我的問題所在。c編程測驗平均數組for循環
#include <stdlib.h>
#include <stdio.h>
#define STUDENTS 4
#define QUIZZES 5
main() {
int quizScores [STUDENTS] [QUIZZES] = {
{ 90, 90, 90, 90, 90 },
{ 90, 80, 70, 60, 50 },
{ 90, 89, 88, 87, 86 },
{ 90, 85, 80, 75, 70 }
};
int studentTotal = 0, quizTotal, row, col;
double studentAverage, quizAverage;
for (row = 0; row < STUDENTS; row++) {
studentTotal = 0;
for (col = 0; col < QUIZZES; col++) {
studentTotal += quizScores[row][col];
}
studentAverage = (double) studentTotal/QUIZZES;
printf("Student %i has average %.2lf\n", row, studentAverage);
}
**for (col = 0; col < QUIZZES; col++) {
quizTotal = 0;
for (row = 0; row < STUDENTS; row++) {
quizTotal += quizScores[col][row];
}
quizAverage = (double) quizTotal/STUDENTS;
printf("Quiz %i has an average %.2lf\n",col, quizAverage);
// output the average for this quiz
}**
system("pause");
}
請注意,調試諸如此類問題的有效方法是在您處理它們時打印正在處理的值。您也可以使用調試器來查看代碼,看看發生了什麼。例如,如果你在第二個循環中打印了'printf(「測驗[%d] [%d] =%f \ n」,col,row,quizScores [col] [row]);''數字隨你走,這會讓你看起來很難看代碼。 –
