This question is not difficult, just pay attention to the output accuracy. But the author is a bit puzzled, the title requires the use of function overloading, I used the C language, and wrote the following code.

#include<stdio.h>
void pow(int a,int b){
    
    
	printf("%d\n",a*a+b*b);
}
void pow(double c,double d){
    
    
	printf("%0.2lf",c*c+d*d);
}
int main(){
    
    
	int a,b,m;
	double c,d,n;
	scanf("%d%d",&a,&b);
	scanf("%lf%lf",&c,&d);
	pow(a,b);
	pow(c,d);
	return 0;
}

Submitted on the official website of the Blue Bridge Cup showed a compilation error. The author thinks that the function is overloaded and the method name should be the same, but the author does not know what is going on when such an error is reported, but when I change it to two different method names It runs correctly.

After changing the method name

#include<stdio.h>
void pow1(int a,int b){
    
    
	printf("%d\n",a*a+b*b);
}
void pow2(double c,double d){
    
    
	printf("%0.2lf",c*c+d*d);
}
int main(){
    
    
	int a,b,m;
	double c,d,n;
	scanf("%d%d",&a,&b);
	scanf("%lf%lf",&c,&d);
	pow1(a,b);
	pow2(c,d);
	return 0;
}
