下面是我写的第一部分,转换成大写字母.,请教大侠们,怎么算字母出现频率和百分比
#include <stdio.h>
#include <stdlib.h>
#include < string.h>
void ToUpper (int);
void PrintResult ( int);
char a[80];
void main ()
{
int c;
printf("please enter a string\n");
gets(a);
while( c !=0)
{
ToUpper( c);
//PrintfResult ( c);
printf("please enter a string\n");
gets(a);
}
}
void ToUpper ( int c)
{
int i;
long l;
l=strlen(a);
for(i=0; i<l;i++)
if (a[i]>96 &&a[i]<123)
a[i]=a[i]-32;
puts(a);
}
