大数阶乘的c语言代码

#include <stdio.h> int main() { int n, i, j, tmp, sum; char num[3000] = { 1 }; scanf( "%d", &n ); for ( i=2; i<=n; i++ ) for ( j=0,tmp=0; j<3000; j++ ) { sum = num[j]*i+tmp; num[j] = sum%10; tmp = sum/10; } i = 2999; while ( !num[i] ) i--; for ( j=i; j>=0; j-- ) printf( "%d",num[j] ); putchar( '\n' ); return 0; }

把结果存放在字符数组里，所以能表示最低位到最高位的所有数字。
