C Program for Gauss Elimination Method to Solve Linear Equations

Updated on May 4, 2012

We all know that Gauss elimintaion method used in mathematics is easier to find the solution of linear equations . Following is the source code for the same method . Just copy the code in your notepad and save it with the extension *.c or *.cpp. Then open the saved file with your Compiler and run it .

#include<stdio.h>
#include<conio.h>
int main()
{
int i,j,k,n;
float a[10][10],c[10],x[10];
printf("****** welcome 2 gauss elimination method *******\n");
printf("\nenter the number of elements: ");
scanf("%d",&n);
printf("Enter constants: ");
for(i=0;i<n;i++)
scanf("%f",&c[i]);
printf("\nenter the matrix: ");
for(i=0;i<n;i++){
for(j=0;j<n;j++)
scanf("%f",&a[i][j]);
}
for(k=0;k<n-1;i++){
for(i=k+1;i<n;i++){
for(j=k+1;j<n;j++){
a[i][j]=a[i][j]-(a[i][k]/a[k][k])*a[k][j];
c[i]=c[i]-(a[i][k]/a[k][k])*c[k];
}
      }
      x[n-1]=c[n-1]/a[n-1][n-1];
      printf("The solution is: \n");
      printf("x[%d]=%f\n",n-1,x[n-1]);
      for(k=0;k<n-1;k++)
      {
i=n-k-2;
for(j=i+1;j<n;j++)
c[i]=c[i]-(a[i][j]*x[j]);
x[i]=c[i]/a[i][i];
printf("x[%d]=%f\n",i,x[i]);
      }
      getch();
      }
}

After running the program , you need to enter the constants as well as coefficient of the three linear equations in the form of matrix . The program thereafter will give you desired result . :)

      What do "elements", "constants" mean there?

      Is it Gauss Naïve or Gauss Jordan method?
