简答题

下面程序的功能是：area函数计算圆的面积，main函数中调用area函数，计算给定半径的圆的面积，输出时显示两位小数。请填空。#include#define PI 3.14int main( ){;float x = 2.4 , y ;y = area( x ) ;printf( "%6.2f\n" , y ) ;return 0 ;}float area ( float r ){float s ;s= PI * r * r ;;}

简答题

下面程序的功能：有一个一维数组score，内放10个学生成绩，统计不及格的学生人数。请填空。#include int main( ){int fun( float array[10] ) ;float score[10] ;int i , count = 0 ;printf( "input 10 scores:\n" ) ;for( i = 0 ; i < 10 ; i++ )scanf( "%f" , &score[i] );;printf( "%d\n" , count ) ;return 0 ;}int fun( float array[10] ){int i , count = 0 ;for( i = 0 ; i < 10 ; i++ )if( array[i] <60 );return count ;}

简答题

下面程序的功能是：fun函数实现将整数n的值逆序转换，转换后的值通过函数值返回，请填空。#include int fun(int n){int m, y = 0;if (n >= 0)m = n;elsem = -n;while (m != 0) {y = y * 10 + m % 10;m = ___(1)_ ;}y = (n >= 0) ? y : -y;_(2)____ ;}int main(){int m1, m2;scanf("%d %d", &m1, &m2);printf("%d的逆向是%d\t", m1, fun(m1));printf("%d的逆向是%d\n", m2, fun(m2));return 0;}

简答题

下面程序中，函数fun的功能是：根据形参c中存储的整数序列，将偶数下标位置的所有偶数元素求和，减去奇数下标位置的所有奇数元素的和，所得差由函数值返回。形参d中存储的是序列的长度。例如，若c中存储的序列依次为：13, 15, 4, 7, 20，d为5，则函数返回 (4+20) - (15+7) = 2，主程序输出2，请填空。#include int fun(int c[ ], int d){int s0 = 0, s1 = 0, i;for (i = 0 ; i < d ; i++){if ((i % 2 == 0) && (c[i] % 2 == 0))s0 += c[i];if ((i % 2 == 1) && (___(1)_))s1 += c[i];}return _(2)____;}main( ){int i, c[100], d;printf("请输入整数序列的长度：");scanf("%d", &d);printf("请输入%d个整数：\n",d);for (i = 0; i < d; i++)scanf("%d", &(c[i]));i = fun(c, d);printf("%d", i);}
