1131: genetic correlation

Be careful ： The first is count Must be double type ,len yes int type ,m=double（count/len）

​
#include<string.h>
#include<iostream>
using namespace std;
int main()
{
    char s1[501],s2[501];
    double count;//count Must be double type  
    double c;
    double m;
    int len;
    int i;
 
    cin>>c>>s1>>s2;
    len=strlen(s1);
    for(i=1; i<=len; i++) 
        if(s1[i]==s2[i])
            count++;
    m=double(count/len);
    if(m>=c)
        cout<<"yes"<<endl;
    else
        cout<<"no"<<endl;
 
    return 0;
}

Pay attention to the second ：len and count Must be double type ,m=count/len perhaps m=double（count/len）

#include<string.h>
#include<iostream>
using namespace std;
int main()
{
    char s1[501],s2[501];
    double len,count;
    double c;
    double m;
    int i;
 
    cin>>c>>s1>>s2;
    len=strlen(s1);
    for(i=1; i<=len; i++) 
        if(s1[i]==s2[i])
            count++;
    m=count/len;
    if(m>=c)
        cout<<"yes"<<endl;
    else
        cout<<"no"<<endl;
 
    return 0;
}
