C:(更改格式化问题和%lld问题版）

#include <stdio.h>
signed main()
{
    long long a;
    long long x;
    long long Fib[60];
    Fib[0] = 0;
    Fib[1] = 1;
    scanf("%lld", &a);
    for (int i = 2; i <= 60; i++)
    {
        Fib[i] = Fib[i - 1] + Fib[i - 2];
    }
    for (int i = 1; i <= a; i++)
    {
        scanf("%lld", &x);
        printf("Fib(%lld) = %lld\n", x, Fib[x]);
    }
    return 0;
}

C :

#include <stdio.h>
signed main()
{
    long long a;
    long long x;
    long long Fib[60];
    Fib[0]=0;
    Fib[1]=1;
    scanf("%lld",&a);
    for(int i=2;i<=60;i++)
    {
        Fib[i]=Fib[i-1]+Fib[i-2];
    }
    for(int i=1;i<=a;i++)
    {
        scanf("%d",&x);
        printf("Fib(%d) = %lld\n",x,Fib[x]);
    }
    return 0;
}

C++ :

#include<iostream>
#include<cstdio>
using namespace std;

int main()
{
    int T,k;
    long long X[61];
    cin>>T;
    
    X[0]=0;
     
    X[1]=1;
    
    for(int i=2;i<=60;i++)
    
    X[i]=X[i-1]+X[i-2];
    
    for(int i=0;i<=T-1;i++)
{   cin>> k;
    printf("Fib(%d) = %lld\n",k,X[k]);
}    
    return 0;
}
