C Program to Generate Random Partition from Given Set

This is a C Program to perform partitioning at random index and generate two sets for given set of numbers or characters

Here is source code of the C Program to Generate Random Partition out of a Given Set of Numbers or Characters. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

int main(int argc, char **argv) {

```
    int i;
```
```
    time_t seconds;
```
```
    time(&seconds);
```
```
    srand((unsigned int) seconds);
```
```
 
```
```
    int noc = rand() % 2;
```

    // if noc is equal to generate numbers

```
    if (noc == 1) {
```
```
        int N = 10;
```
```
        int sequence[N];
```

        printf("The Original set of numbers are:\n  ");

```
        for (i = 0; i < N; i++) {
```

            sequence[i] = rand() % (100 - 1 + 1) + 1;

```
            printf("%d ", sequence[i]);
```
```
        }
```
```
 
```

        int partition_index = rand() % 11;

        printf("\nThe two sequences are: ");

```
        printf("{ ");
```
```
        for (i = 0; i < N; i++) {
```
```
            if (i == partition_index)
```
```
                printf(" } and { ");
```
```
            printf("%d ", sequence[i]);
```
```
        }
```
```
        printf("}");
```

        printf("\nPartitioning around index %d", partition_index);

```
 
```
```
    }
```
```
    // else generate characters
```
```
    else {
```
```
        int N = 10;
```
```
        char sequence[N];
```

        printf("The Original set of characters are:\n  ");

```
        for (i = 0; i < N; i++) {
```

            sequence[i] = (char) (rand() % (123 - 97 + 97) + 97);

```
            printf("%c", sequence[i]);
```
```
        }
```
```
 
```

        int partition_index = rand() % 11;

        printf("\nThe two sequences are: ");

```
        printf("{ ");
```
```
        for (i = 0; i < N; i++) {
```
```
            if (i == partition_index)
```
```
                printf(" } and { ");
```
```
            printf("%c", sequence[i]);
```
```
        }
```
```
        printf("}");
```

        printf("\nPartitioning around index %c", partition_index);

```
 
```
```
    }
```
```
    return 0;
```
```
}
```

Output:

$ gcc RandomPartition.c
$ ./a.out
 
The Original set of numbers are:
  52 49 7 78 82 78 30 27 51 66 
The two sequences are: { 52 49 7 78 82 78  } and { 30 27 51 66 }
