C語(yǔ)言數(shù)組指針的小例子

    1、功能：輸入6個(gè)學(xué)生的5門(mén)課程成績(jī)，計(jì)算出每個(gè)學(xué)生的平均分和每門(mén)課程的平均分。
    2、C語(yǔ)言實(shí)現(xiàn)代碼：（其實(shí)就是用二維數(shù)組來(lái)實(shí)現(xiàn)的，二維數(shù)組的引用傳遞使用數(shù)組指針來(lái)完成）
    復(fù)制代碼 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);
    }
    }
