c quetions

a)write a function calculating how many times immediataly repeating letters (mm,oo) appear in the string

b)write main function to input a string from the keyboard,call function from a) and print the result

google

1）写一个函数计算多少次立即还重复的字母（mm，00）出现在字符串

二）写输入的主要职能从从a）和打印结果键盘，调用函数的字符串

这翻译！
#include<stdio.h>

unsigned TimesIR(char*);

int main(void)
{
char t[80];
gets(t);
unsigned num=TimesIR(t);
printf("%u\n", num);
return 0;
}

unsigned TimesIR(char* s)
{
int i=0;
unsigned count=0;
while(s[i]!='\0')
{
if(s[i]==s[i+1])
{
++count;
++i;//连续的三个算一次重复，如果需要算两次，去掉这句
}
++i;
}
return count;
}

"google"有1次oo，"gooogle"当做一次ooo还是两次oo？我这里算作两次：

#include<stdio.h> #include<string.h> int getrepeat(char* a){ int i,m,n; m=0; n=strlen(a); for(i=0;i<n-1;i++){ if(a[i]==a[i+1]) m++; } return m; } main() { char a[]="google"; printf("%d\n",getrepeat(a)); }
