converting integers to Strings

Because the 64-bit Int_max has a length of not more than 20, the string array is passed into the function.

intNUM2STR (intNumCharstr[]) {    CharC; intI=0, j=0, k=0, TMP = num >0? Num:-1*num; if(num > Int_max | | num < int_min)return-1; if(num<0) {Str[i++] ='-'; ++J; Num*= -1;//The remainder requires attention to be converted to a positive number because -1111%10==-1    }    Else if(0==num) {str[0] ='0'; str[1] =' /';return 0; }     while(TMP) {Str[i]= tmp%Ten+'0'; ++i; TMP/=Ten; } k= i-1;  while(j<k)//String Conversions{C=Str[j]; STR[J]=Str[k]; STR[K]=C; J++; k--; } Str[i]=' /'; return 0;}

The case where integers are positive or negative is considered, but there is a problem, and if the number passed in main is overflow, the numbers in the function are very different.
