TUGAS PENDAHULUAN MODUL 6

Tugas Pendahluan :
1. #include <stdio.h>
void permutasi()
{
int n,r,x,y,i,j,p;
printf ("============================

========\n");

printf ("\t Mencari Permutasi \n");
printf ("====================================\n");
printf ("Masukan nilai n : "); scanf("%d",&n);
printf ("Masukan nilai r : "); scanf("%d",&r);
if (n>r)
{

x=1;
y=1;
for (i=1;i<=n;i++)
{x=x*i;}
for (j=1;j<=(n-r);j++)
{y=y*j;}
p = x/y;
printf ("Permutasi P(%d,%d) : %d",n,r,p);
}
else
printf ("Permutasi P(%d,%d) : Tidak valid",n,r);
}
main()
{permutasi ();}


2. Soalnya aja ga jelas jadi ngapaen di kerjakan heheheheehe.....

Tugas Praktikum
1. #include <stdio.h>
#include <math.h>

printf ("Luas Segitiga : %.2lf",L);
}
void sisi_miring()

Silahkan dikembangkan sendiri ya.............................??????????? Happy - yippy- yahui.
