C++ 創(chuàng)建桌面快捷方式 開始菜單的實現代碼

    1、功能：輸入6個學生的5門課程成績，計算出每個學生的平均分和每門課程的平均分。
    2、C語言實現代碼：（其實就是用二維數組來實現的，二維數組的引用傳遞使用數組指針來完成）
    代碼如下:
    #include <stdio.h>
    #define STUDENT 5
    #define SCORE 6
    void input_array(float (*score)[STUDENT]);
    void avg_score(float (*score)[STUDENT]);
    void avg_course(float (*score)[STUDENT]);
    /**
    * calculate student average score and course average socore.
    */
    int main(){
    float a[SCORE][STUDENT];
    input_array(a);
    avg_course(a);
    avg_score(a);
    }
    void input_array(float (*score)[STUDENT]){
    int i, j;
    for(i=0; i<SCORE; i++){
    printf("input the %d student score:", i+1);
    for(j=0; j<STUDENT; j++){
    scanf("%f", score[i] + j);
    }
    }
    }
    void avg_course(float (*score)[STUDENT]){
    int i,j;
    float s;
    for(j=0; j<STUDENT; j++){
    printf("course%d ", j);
    }
    printf("n");
    for(i=0; i<SCORE; i++){
    s=0;
    for(j=0; j<STUDENT; j++){
    printf("%f ", *(score[i] + j));
    s += *(score[i] + j);
    }
    printf("ts=%f, avg=%fn" , s,s/STUDENT);
    }
    }
    void avg_score(float (*score)[STUDENT]){
    int i,j;
    float s;
    for(i=0; i<STUDENT; i++){
    s = 0;
    for(j=0; j<SCORE;j++){
    s+= *(score[j]+i);
    }
    printf("%f " , s/SCORE);
    }
    }
