hello everybody

please i shall be very obliged to those who shall help me solving these problems
please,,help me

i want to make a function SumDiagonal that take in a 2 dimensional array (of 2rows and 2 coloumn) called dimtwoarray containing integers.your function should total up the integers in the diagonal (that is row=coloumn cells).

please help me writing a funtion addsubarrray that take in a 3 dimensional array(of eg 1 row,2 coloumn and 3 widths) containing integers.the function should add 1 to even numbers and subtract 1 from odd numbers in the array.please i want to coding to be done appropriately,i am confused in its coding part, though a bit of logic is known.

please get me the code of function countvowel that take in a string parameter and return the number of non vowels (vowels are a,e,I,o,u) in it.string library is not to be used.

i want to make a function removespaces that would take in a string parameter and return the string without the blank spaces. but string library is not allowed to be used.

Thats not too hard..
Create an array called temp equal to the size of the array of characters your removing white spaces from. copy one letter at a time from array1 to temp ommittin all tabs, spaces, carriage return/newlines...

I cant remember exactly, \r or \c might not be anything in c.

ex. \t, \n, \r, \c

int SumDiagnol(int dimtwoarray[2][2])
{
    return(dimtwoarray[0][0] + dimtwoarray[1][1]);
}

I did this off the top of my head...it hasn't been tested, but it gives the general idea

void modifyarray(int a)
{
for (int x=0;x<1;x++)
for (int y=0;y<2;y++)
for (int z=0;z<3;z++)
{
if (a[x][y][z] % 2 == 0)
a[x][y][z] = a[x][y][z] + 1;
else
a[x][y][z] = a[x][y][z] - 1;
}
}

void main()
{
int a[1][2][3];
for (int x=0;x<1;x++)
for (int y=0;y<2;y++)
for (int z=0;z<3;z++)
a[x][y][z]=0;
modifyarray(a);
}

int countvowel(char *p)
{
        char ch;
       int i;

       for (i = 0; *p; ++p)
        {
                ch = *p & 0xDF;
                if (ch < 'B' || ch > 'Z')
                        continue;
               if (ch != 'E' && ch != 'I' && ch != 'O' && ch != 'U')
                       ++i;
       }
       return(i);
}

char *removespaces(char *str)
{
        char *p1;
       char *p2;

        for (p1 = p2 = str; *p1; ++p1)
                if (*p1 != ' ')
                        *(p2++) = *p1;
        return(str);
}

Oops. Forgot the null terminator.

char *removespaces(char *str)
{
    char *p1;
    char *p2;
    for (p1 = p2 = str; *p1; ++p1)
        if (*p1 != ' ')
            *(p2++) = *p1;
    *p2 = 0;
    return(str);
}
