C Program to Reverse every Word of given String

#include < stdio.h>
#include < string.h>
 
void main()
{
    int i, j = 0, k = 0, x, len;
    char str[100], str1[10][20], temp;
 
    printf("enter the string :" );
    scanf("%[^\n]s" , str);
 
/* reads into 2d character array */
    for (i = 0;str[i] != '\0'; i++)
    {
        if (str[i] == ' ')
        {
            str1[k][j]='\0';

        }
    }

    for (i = 0;i <= k;i++)
    {
        len = strlen(str1[i]);
        for (j = 0, x = len - 1;j < x;j++,x--)
