Hi,

I have written code for only 3 digit numbers(u may not get
exact result for 100, 200, 113 etc ). This is just for an
idea from which u can build ur logic.
I accept... This code can be optimised.

Dont think that code is too lengthy... cos we hav to hav
limited if, else if or switch for this requirement.

Apply ur logic for 123455677 kind of nos.

#include <stdio.h>
/*Convert no to word... only for 3 digit nos*/
void ConvertToWord(int length);
char* Tens(int *a);
int Temp[10], Length = 0;

int main()
{
int No = 999, DupNo, i, j;
printf("ENTER THE THREE DIGIT NO: ");
scanf("%d", &No);
DupNo = No;
while(DupNo != 0)
{
Temp[Length] = DupNo % 10;
DupNo = DupNo / 10;
Length++;
}
printf("%d - ", No);
ConvertToWord(Length);
_getch();
}


void ConvertToWord(int Length)
{
while(Length != 0)
{
switch(Length)
{
case 0:
break;
case 1:
switch(Temp[Length - 1])
{
case 0:
break;
case 1:
printf("ONE ");
break;
case 2:
printf("TWO ");
break;
case 3:
printf("THREE ");
break;
case 4:
printf("FOUR ");
break;
case 5:
printf("FIVE ");
break;
case 6:
printf("SIX ");
break;
case 7:
printf("SEVEN ");
break;
case 8:
printf("EIGHT ");
break;
case 9:
printf("NINE ");
break;
}
Length--;
break;

case 2:
switch(Temp[Length -1])
{
case 0:
break;
case 1:
break;
case 2:
printf("TWENTY ");
break;
case 3:
printf("THIRTY ");
break;
case 4:
printf("FORTY ");
break;
case 5:
printf("FIFTY ");
break;
case 6:
printf("SIXTY ");
break;
case 7:
printf("SEVENTY ");
break;
case 8:
printf("EIGHTY ");
break;
case 9:
printf("NINETY ");
break;
}
Length--;
break;

case 3:
printf("%s HUNDRED AND ", Tens(&Temp[--
Length]));
break;
}
}

}

char* Tens(int *a)
{
char *ch;
switch(*a)
{
case 0:
ch = "ZERO";
break;
case 1:
ch = "ONE";
break;
case 2:
ch = "TWO";
break;
case 3:
ch = "THREE";
break;
case 4:
ch = "FOUR";
break;
case 5:
ch = "FIVE";
break;
case 6:
ch = "SIX";
break;
case 7:
ch = "SEVEN";
break;
case 8:
ch = "EIGHT";
break;
case 9:
ch = "NINE";
break;
}
return ch;
}

Write a program to replace n bits from the position p of the bit representation of an inputted character x with the one's complement. Method invertBit takes 3 parameters x as input character, p as position and n as the number of positions from p. Replace n bits from pth position in 8 bit character x. Then return the characters by inverting the bits.
