大佬们#include <stdio.h>int main(void){ int a,b,c; int xx=0;puts("请输入两个整数:");printf("整数1:"); scanf("%d",&a);printf("整数2:"); scanf("%d",&b);if (a>b){xx=b;}do {xx+=b;b++;} while(b<=a);printf("大于等于%d小于等于%d的全部和是%d",b,a,xx);else{xx=a;}do{xx+=a;a++;} while(a<=b);printf("大于等于%d小于等于%d的全部和是%d",a,b,xx);return (0);}这花括号咋加哭了
