如何使得输入小数时不运行if和while中的内容！

#include<stdio.h>
#include

int main() {
int val = 0, sum = 0, currval = 0;

if (std::cin >> currval) {
    sum += 1;
        while (std::cin>>val) {
            if (val == currval) {
                sum += 1;
            }
            else {
                std::cout << "整数：" << currval << "出现的次数为：" << sum << std::endl;
                sum = 1;
                currval = val;
            }
        }
    
    std::cout << "整数：" << currval << "出现的次数为：" << sum << std::endl;
}
return 0;

}

把
currval定义为string或者char [],然后再根据string的内容确定
