#include <stdio.h>
#include <conio.h>
main()
{
char str[100] = {0};
printf( "input:\n" );
scanf( "%s",str );
int i = 0;
if( str[0]>='a' && str[0]<='z' ) str[0]=str[0]-'a'+'A';
while( str[i] != '\0' )
{
if( str[i] == ' ' )
{
if( str[i+1]>='a' && str[i+1]<='z' )
{
str[i+1]=str[i+1]-'a'+'A';
i++;
}
}
}
}

忘了输出，补上
#include <stdio.h>
#include <conio.h>
main()
{
char str[100] = {0};
printf( "input:\n" );
scanf( "%s",str );
int i = 0;
if( str[0]>='a' && str[0]<='z' ) str[0]=str[0]-'a'+'A';
while( str[i] != '\0' )
{
if( str[i] == ' ' )
{
if( str[i+1]>='a' && str[i+1]<='z' )
{
str[i+1]=str[i+1]-'a'+'A';
i++;
}
}
}
printf( "\n%s\n",str );
getch();
}
