Integer to string

Integer to string

Use recursion to convert an integer n into a string. For example, if you enter 483, the string "483" should be output. The number of digits of n is uncertain and can be a positive integer of any number of digits.

The input is only one line and contains a positive integer not exceeding 1000000.

Output the corresponding string.
Please pay attention to the line ending output.
enter

123875

Output

123875

    char *p=a;
    long int n;
    cin>>n;
    while (n>0)

        *p=n%10+48;		//字符‘0’的ASCII
        n/=10;
