输出 This Is A Test Program
用C语言

Answer 1

已通过测试运行,正常.有问题加我q23824056

#include<stdio.h>
#include<string.h>
main()
{
char *ptr, *ptr1;
ptr = (char *)malloc(256);
ptr1 = (char *)malloc(256);
memset(ptr, 0, sizeof(ptr));
memset(ptr1, 0, sizeof(ptr1));
printf("please input an English sentence:");
gets(ptr);

ptr1 = ptr;

*ptr -= 32;
while(*ptr!='\0')
{
if(*ptr==' '){ *(ptr+1) -= 32; }
ptr++;
}
puts(ptr1);
getch();
}

Answer 2

word就可以实现。格式，更改大小 写

Answer 3

#include<stdio.h>
#include<string.h>
main()
{
char *ptr, *ptr1;
ptr = (char *)malloc(256);
ptr1 = (char *)malloc(256);
memset(ptr, 0, sizeof(ptr));
memset(ptr1, 0, sizeof(ptr1));
printf("please input an English sentence:");
gets(ptr);

ptr1 = ptr;

*ptr -= 32;
while(*ptr!='\0')
{
if(*ptr==' '){ *(ptr+1) -= 32; }
ptr++;
}
puts(ptr1);
getch();
}

方法1限制单词长度:

#include <ctype.h>
#include <stdio.h>
#include <string.h>

int main()
{
char c, *pstr;
char szWord[16];

while(1)
{
pstr = szWord;
while((c = getchar()) != ' ' && c != '\n' && c != EOF)
{
*pstr++ = c;
}
if(c == ' ')
*pstr++ = ' ';

*pstr = '\0';
*szWord = toupper(*szWord);

printf("%s", szWord);;
memset(szWord, 0, 16);

if(c == '\n' || c == EOF)
break;
}
}

方法二限制句子长度:

#include <ctype.h>
#include <stdio.h>

int main()
{
char szLine[64], *pstr = szLine;
char c;

gets(szLine);

do{
if(isalpha(*pstr))
{
*pstr = toupper(*pstr);
}
while(*pstr++ != ' ' && *pstr != '\0');
}while(*pstr != '\0');

printf("%s", szLine);
}
