program needed

Hi
please find the code below. i have tested the program in linux. it might give some minor error in turbo-c but i hope u can correct those.

#include<stdio.h>

void drawPascalTriangle(int rows);
void getRow(int *prevRow, int prevRowSize, int *row);
void copyRow(int *prevRow, int *row, int rowSize);
void dispRow(int *row, int rowSize, int rows);

int main()
{
	int rows;
	printf("Enter no. of rows:");
	scanf("%d", &rows);
	
	drawPascalTriangle(rows);
	return 0;
}

void drawPascalTriangle(int rows)
{
	int prevRow[50];
	int row[50];
	int prevRowSize = 0;
	int rowSize = 0;
	int i;
	for(i=0;i<rows;i++)
	{
		getRow(prevRow, i, row);
		dispRow(row, i+1, rows);
		printf("\n");
		copyRow(prevRow, row, i+1);
	}
}

void getRow(int *prevRow, int prevRowSize, int *row)
{
	int i;
	for(i=0;i<prevRowSize;i++)
	{
		if(i==0)
		{
			*row = *prevRow;
		}
		else
		{
			*row = *(prevRow) + *(prevRow-1);
		}
		row++;
		prevRow++;
	}
	*row = 1;
}
void copyRow(int *prevRow, int *row, int rowSize)
{
	int i;
	for(i=0;i<rowSize;i++)
	{
		*prevRow = *row;
		prevRow++;
		row++;
	}
}
void dispRow(int *row, int rowSize, int rows)
{
	int i;
	for(i=0;i<rows-rowSize;i++)
		printf("    ");
	for(i=0;i<rowSize;i++)
	{
		printf("%4d    ", *row);
		row++;
	}
}

Stop hijacking threads. Start a new thread and learn how to read. Did you not read my previous post?

SHOW SOME EFFORT!! Your request and that of the OP just show how bloody well lazy the both of you are.

Sheesh.
