c - Nested for loop array random numbers -


so trying print out 7 random numbers , loop should not print out duplicates. when trying debug seems don't in nested loop if statement is.

i memory value printed out , random numbers duplicated.

i believe there wrong in 2nd nested loop cant figure out what, appreciate if can see issue , explain me what's happening nested 2nd loop, step step.

#include <stdio.h> #include <time.h> #define size 35  int main() { int number[size];  srand(time(null));  (int = 1; < 7; i++) {     number[i] = rand() % 35 + 1;     (int j = 0; j > i; j++)     {         if (number[i] == number[i])         printf("%d\n", number[i]);         i--;     } } (int = 0; < 7; i++) {     printf("%d\n", number[i]); } getchar();  return 0; }

for starters loop

for (int j = 0; j > i; j++)

will executed never because j initialized such way less i.

the program can following way

#include <stdlib.h> #include <stdio.h> #include <time.h>  #define size    35  int main(void)  {     int number[size];     int n = 7;      int = 0;      srand( ( unsigned int )time( null ) );      while ( < n )     {         int value = rand() % size + 1;          int j = 0;         while ( j < && number[j] != value ) j++;          if ( j == ) number[i++] = value;     }      ( = 0; < n; i++ ) printf( "%d ", number[i] );     putchar( '\n' );      getchar();      return 0; }

its output might be

10 21 16 17 26 25 34
