C++ computer programming question 2.please help!?

Write a function with int* argument a and int arguments length and x which returns the number of elements x in the memory block a.


The following sample tasks may help:





sample task 1


write a function with a const char* arguments, an int argument length and a character argument c,which which returns the number of characters c in s








int count(const char* s, int length, char c)


{


int i, cnt;


for(i=0, cnt=0; i%26lt; length; ++i)


if(*(s + 1) == c)


++cnt;


return cnt;


}








sample task 2:


write a function with int* argument a and int argument length which reurns the maximum element in the memory block a





int max_element(int* a, int length)


{


int i, max;


for (max = *a, i=1; i%26lt;length; ++1)


if(max%26lt; *(a+i))


max= *(a+i);


return max;


}

int countIt(int* a, int length, int x)


{


int finds =0;


int i;


for (i=0; i%26lt;length; ++i)

finds++;


}


return finds;
