I need some help creating a nested loop in the last for loop of columns of the matrix...
The program accepts input and creates output. It is pretty much a Coef System of linear equations
1.0 2.0 3.0 10.0
4.0 5.0 6.0 20.0
7.0 8.0 9.0 30.0
Here is the code:
#include<stdio.h>
#include<conio.h>
#include<math.h>
void (main void)
{
int i,j;
FILE*outptr;
outptr=fopen("matrix.txt","wt")
double x,y;
double A[3][3],B[3],X[3];
fprint(outptr,"This is a coefficient of linear equations\n")
printf("Please enter A[3][3] Row by Row: \n")
for(i=0;i<3;i++)
for(j=0;j<3;j++)
scanf("%lf",&A[i][j]);
printf("Please enter B[3], and the RHS vector, starting from row 1: \n")
for(i=0;i<3;i++)
scanf("%lf",&B[i]);
printf("\n")
for(i=0;i<3;i++)
{
printf("%3.1lf %3.1lf %3.1lf %3.1lf", A[i][0],A[i][l]\
,A[i][2],B[i]);
fprintf(outptr,"3.1lf %3.1lf %3.1lf %3.1lf\n",\
A[i][0],A[i][l],A[i][2],B[i]");
fprintf(outptr, "\n");
}
getch();
fclose(outptr)
}
