产生a到b的随机数

#include <cstdlib>#include <iostream>#include<stdlib.h>using namespace std;int myRand(int a,int b){        return (a>=b)?0:(a+rand()%(b-a));}int main(int argc, char *argv[]){    for(int i=0;i<10;i++){        int c= myRand(1,100);        cout<<"c="<<c<<endl;    }    system("PAUSE");    return EXIT_SUCCESS;}
