Gauss–Seidel Method

Write a program in C to solve the following system using the Gauss–Seidel Method:
𝟏𝟎𝒙 + 𝒚 + 𝒛 = 𝟏𝟐𝒙 + 𝟏𝟎𝒚 + 𝒛 = 𝟏𝟑𝒙 + 𝒚 + 𝟏𝟎𝒛 = 𝟏4

#include <stdio.h>
#include <conio.h>
int main(){
 clrscr();
 double x=0,y=0,z=0,x1,y1,z1;
 for(int k=0;k<10;k++){
 x1=(12 - y - z)/10
 y1=(13 - x1 - z)/10;
 z1=(14 - x1 - y1)/10;
 x=x1; y=y1; z=z1;
 }
 printf("\n\n\tx=%.4f\ny=%.4f\nz=%.4f\n",x,y,z);
 getch();
 return 0;
}

Output
