恩 刷回PAT。     原题描述如下 Calculate a + b and output the sum in standard format -- that is, the digits must be separated into groups of three by commas (unless there are less than four digits). Input

#include int main ( ) { int i , j , K1 , K2 ; int a , B[1001] ; float A[1001] = {0} , b ; scanf("%d",&K1 ); for ( i = 1 ; i <= K1 ; i++ ) { scanf("%d %f",&a, &b );
