代码如下：

//计算1*2*3+3*4*5+5*6*7+...+99*100*101的值
#include<stdio.h>
int main() {
	long i;
	long term, sum = 0;
	for (i = 1; i <= 99;i+=2) {
		term = i*(i + 1) * (i + 2);
		sum = sum + term;
		printf("term=%ld*(%ld + 1) * (%ld + 2)\n",i,i,i);
		printf("sum=%ld\n",sum);
		printf("\n");
	}
	printf("sum=%ld\n",sum);
}

程序运行结果如下：
