华为C语言机试题面试题汇总[共38页]

1第一题的题目大概是输入整型数组求数组的最小数和最大数之和，例如输入1,2,3,4则输出为5，当输入只有一个数的时候，则最小数和最大数都是该数，例如只输入1，则输出为2；另外数组的长度不超过50#include<stdio.h>main()         int num50=0;         int i,n;          printf("请输入整型数组的长度(150)：");         scanf("%d",&n);                    printf("请输入整型数组的元素：");         for (i=0;i<n;i+)                            scanf("%d",&numi);                        int min_num=num0;         int max_num=num0;         for(int j=0;j<n;j+)                            if(max_num<numj)                            max_num=numj;                   else if(min_num>numj)                            min_num=numj;                  int sum=min_num+max_num;         printf("数组中最大与最小值之和：%dn",sum);         return 0; 2求两个长长整型的数据的和并输出，例如输入1233333333333333 。 3111111111111111111111111.。，则输出。#include<stdio.h>#include<string.h>#include<malloc.h>main()         char *num1,*num2;  /两个长长整型数据         char *sum;/      int

*pInputStr, long lInputLen, char *pOutputStr);【输入】 pInputStr：输入字符串lInputLen：输入字符串长度【输出】 pOutputStr：输出字符串，空间已经开辟好，与输入字符串等长；#include <stdio.h>#include<string.h>#include<malloc.h>void stringFilter(const

printf("%sn",outstr);         free(outstr);         outstr = NULL; 4.通过键盘输入一串小写字母(az)组成的字符串。请编写一个字符串压缩程序，将字符串中连续出席的重复字母进行压缩，并输出压缩后的字符串。压缩规则：1. 仅压缩连续重复出现的字符。比如字符串"abcbc"由于无连续重复字符，压缩后的字符串还是"abcbc".2. 压缩字段的格式为"字符重复的次数+字符"。例如：字符串"xxxyyyyyyz"压缩后就成为"3x6yz" 要求实现函数：void stringZip(const char *pInputStr, long lInputLen, char *pOutputStr); 【输入】 pInputStr： 输入字符串lInputLen： 输入字符串长度【输出】 pOutputStr： 输出字符串，空间已经开辟好，与输入字符串等长；#include

stringZip(str,len,outstr);         printf("压缩之后的字符串为：%sn",outstr);         free(outstr);         outstr = NULL;5.通过键盘输入100以内正整数的加、减运算式，请编写一个程序输出运算结果字符串。输入字符串的格式为：“操作数1 运算符 操作数2”，“操作数”与“运算符”之间以一个空格隔开。 补充说明：1. 操作数为正整数，不需要考虑计算结果溢出的情况。2. 若输入算式格式错误，输出结果为“0”。 要求实现函数：void arithmetic(const char *pInputStr, long lInputLen, char *pOutputStr); 【输入】 pInputStr： 输入字符串lInputLen： 输入字符串长度【输出】 pOutputStr： 输出字符串，空间已经开辟好，与输入字符串等长；#include <stdio.h>#include<string.h>#include<stdlib.h>void arithmetic(const char *input, long len, char *output)         char s110;         char
