编写一个c语言程序，输入一个字符串，将小写字符转换成大写字符，要求转换用一个函数实现 C语言编程，从键盘输入一字符串，将其中的小写字母全部转换成大...

刚刚回答过一模一样的问题，不知道是不是你重复提问，代码如下：
#include <stdio.h>
void conv(char * p);
int main(void)
{
char str[100];
printf("输入字符串：");
gets(str);
conv(str);
puts(str);
return 0;
}
void conv(char * p)
{
while(*p!='\0')
{
if(*p>='a' && *p<='z')
*p-=32;
p++;
}
}
#include <stdio.h>
#include <string.h>
char* capitalize(const char* source)
{
//声明为静态类型，否则函数返回后栈区释放，返回的数据不确定
static char des[1000]={0};
char* r=des;
while(*source !='\0')
{
if(isalpha(*source)) //判断是否是字母
{
*r++ = *source++ & 0xDF; //转换为大写字母
}else{
*r++ = *source++;
}
}
//*r++ = '\0';
return des;
}
