How you create a table in C programming language?

Answer 1

Well, I don't know what do you mean by table, but here you are:

int main (void)

{

puts ("A3 B3 C3");

puts ("A2 B2 C2");

puts ("A1 B1 C1");

return 0;

}

Answer 2

#include <iostream>

using namespace std;

#define MIN 1

#define MAX 20

int main()

{

// Initialise some variables.

int h,x,y,z,num;

int** ppArray;

char* pLine;

char* p;

char c;

// Begin looping.

do

{

cout<<"Enter a number from "<<MIN<<"-"<<MAX<<" (0 to quit): ";

cin >> num;

while(cin.fail() num<0 num>MAX )

{

if( cin.fail() )

{

cin.clear();

cin >> c;

}

cout << "Invalid number, try again: ";

cin >> num;

}

if(num)

{

// Allocate array memory.

ppArray=new int*[num];

for(z=0;z<num;++z)

ppArray[z]=new int[num];

// Allocate line memory.

z=num*6;

pLine=new char[z+5];

memset(pLine,32,3);

p=&pLine[0];

p+=3;

memset(p,0x2d,z*sizeof(char)); p+=z;

memset(p,0x0a,sizeof(char)); ++p;

memset(p,0x00,sizeof(char));

// Create table.

for(x=0;x<num;++x)

for(y=0;y<num;++y)

ppArray[x][y]=(x+1)*(y+1);

// Print title.

cout<<"\nMULTIPLICATION TABLE\n";

cout<<"====================\n\n";

// Print column header.

cout<<" ";

for(h=0;h<num;)

cout<<++h<<" "<<(h<9?" ":"");

cout<<endl;

cout<<pLine;

// Print rows.

for(x=0;x<num;++x)

{

// Print row header.

cout<<(x<9?" ":"")<<x+1<<" ";

// Print row values.

for(y=0;y<num;++y)

{

z=ppArray[x][y];

cout<<"| "<<z<<(z<10?" ":z<100?" ":" ");

}

cout<<"|\n";

}

cout<<pLine<<endl;

// Tidy up.

for(z=0;z<num;++z)

delete[] ppArray[z];

delete[] ppArray;

delete[] pLine;

}

}while( num );

return(0);

}
