{
char* temp = str1;
int count =0;
while(*str != NULL)
{

{
str++;
temp++;
if(*temp == NULL)
count++;
}
temp = str1;
if(*str != *temp)
str++;
}
return count;
}

///if function is called like

char* str = "ashashushuaashu";
char* str1 = "ashu";
int count = findoc(str,str1);
printf("%d",count);
///it prints 2, because str1 is appears 2 times in str
