Question

The user enters how many characters the password must be made of, then clicks a Generate button. The output is then a string made of numbers, letters (some of are upper case and some are lower case) along with any other characters you wish to use. The code must use a For loop and no other type of loop. The code must also use the Chr string functions, along with the Random function. The Random function generates a number (you need to figure out the range). The number generated is then used in the Chr function as the ASCII value to generate a character. The code must randomize using a letter, upper case or lower case, a number or some other characters.

Explanation / Answer

#include <stdio.h>
#include<stdlib.h>
int main() {
   int len,value,top=0,i;
   char *str;
   printf("ENter the length of the password ");
   scanf("%d ",&len);
   str=(char *)malloc(len*sizeof(char));
   for(i=0;i<len;)
   {
value= rand() % 122;
printf("value is %d ",value);
if(value+48<122){
   str[top]=value+'0';
   printf("strtop is %c ",str[top]);
   top++;
i++;
}
   }

   printf("%s isstring ",str);
   return 0;
   }
