求壹道C語言編程題

樓主，樓上不太會說話，不要理，等等我貼出代碼。沒有其他語言基礎的C語言初學者起步是慢了壹點，但是要渣油~

#include <stdio.h>

int main()

{

int i, n, t1 = 1, t2 = 1, nextTerm,ct=0;

//printf("輸出幾項: ");

//scanf("%d", &n);

n=20;

printf("斐波那契數列: \n");

for (i = 1; i <= n; ++i)

{

printf("%d ", t1);ct+=1;

if(ct%5==0)printf("\n");

nextTerm = t1 + t2;

t1 = t2;

t2 = nextTerm;

}

return 0;

}
