语法没有错误，内容上我按我的意思改了一下，你看这是不是你原来的目的：include <stdio.h> int main(){ int i, j ;int prime ;for( i=2 ; i<100 ; i++ ){ prime = 1 ;for( j=2 ; j<i ; j++ ){ if( i % j == 0 ){ prime = 0 ;break;} if( prime ){ printf(...

Simon has a prime numberxand an array of non-negative integersa1, a2, ..., an. Simon loves fractions very much. Today he wrote out number on a piece of paper. After Simon led all fractions to a common denominator and summed them up, he got a fraction: ...
