char string[100], str[10], c[10];
int z, occ = 0, i = 0, j = 0, count = 0, len = 0;
printf("Enter a string:");

printf("Enter the word to check its occurence:");
scanf("%s", str);

for (j = 0, z = i;j < len; j++, z++)
{
c[j] = string[z];
if (c[j] == str[j])
{
count++; /* Incrementing the count if the characters of the main string match with the characters of the given word */
}
}
if (count == len && string[z] == ' ')
{
occ++; /* Incrementing the occ if word matches completely and next character in string is space */
}
}
printf("The number of occ is %d\n", occ);
}
Output:
Enter a string:welcome to executecodes c programming class, welcome again to c class
Enter the word to check its occurence:welcome
The number of occ is 2
