输出三角数

#include<stdio.h>int tri(int data);int main() {    int count;    for (count = 0; count <= 100; count++) {        tri(count);    }    return 0;}int tri(int data) {    int total = 0;    for (int i = 0; i <= data; i++) {        total += i;        if (data == total)            printf("%d is triangular.\n", data);    }    return data;}
