Here, we have computed the average of n numbers entered by the user. Access elements out of its bound! Suppose you declared an array of 10 elements. Let's say, int testArray[10]; You can access the array elements from testArray[0] to testArray[9]. Now let's say if you try to ...
i in s: sum = sum + 1 #元素个数 all = all + i average = all / sum ...
printf("average score is %5.2f",av); return0; } 本程序首先定义了一个实型函数aver,有一个形参为实型数组a,长度为5。在函数aver中,把各元素值相加求出平均值,返回给主函数。主函数main 中首先完成数组sco的输入,然后以sco作为实参调用aver函数,函数返回值送av,最后输出av值。 从运行情况可以看出,程序实...
