The following is a reference program

 
#include  
#include 
using namespace std; 
//the string is converted into digital 
Int stringToInt (char * s) {
Int len=strlen (s); 
Int ans=0; 
for(int i=0; i If (s [I] <[I] '0' | | s & gt; '9') break; 
Ans *=10; 
Ans +=(s [I] - '0'); 
} 
Return ans. 
} 
//arg c for the parameters of the receiving number + 1, argv parameters for the received array 
Int main (int arg c, char * argv []) 
{
int num=0; 
//parameter number is 2, no error 
If (arg c! {
=3)Cout<" Call the parameter error "& lt; return 0; 
} 
//get cycles 
Num=stringToInt (argv [1]); 
//output 
for(int i=0; iCout} 
return 0; 
}
