Thread: Simple program...simple problem?

Don't know why but it dosent print out the right numbers, and prints out numbers that dont make any sence at all

Code:

#include <stdio.h>
# define MAX 21
int main(void){
double Top_Temp,Right_Temp,Bottom_Temp , Left_Temp, Tolerance;
int Grid_Colums,Grid_Rows, i,j,Iterations;
double Log[MAX][MAX];


printf("Enter the top side temp:");
scanf("%lf",&Top_Temp);
printf("Enter the right side temp:");
scanf("%lf",&Right_Temp);
printf("Enter the bottom side temp:");
scanf("%lf",&Bottom_Temp);
printf("Enter the left side temp:");
scanf("%lf",&Left_Temp);

printf("How many rows in the grid?");
scanf("%i",&Grid_Rows);
printf("How many columns in the grid?");
scanf("%i",&Grid_Colums);



printf("\n");
printf("\n");
printf("\n");
printf("\n");
printf("\n");




///preset all values to 0 or whatever the sides are
for(i=1;i<=Grid_Colums;i++){
for(j=1;j<=Grid_Rows;j++){
if(j==1){
Log[i][j]=Left_Temp;
}
else if(i==1 && j!=1 && j!=Grid_Rows){
Log[i][j]=Top_Temp;
}
else if(j==Grid_Rows){
Log[i][j]=Right_Temp;
}
else if(i==Grid_Colums && j!=1 && j!=Grid_Rows){
Log[i][j]=Bottom_Temp;
}
else{
Log[i][j]=0.0;
}
}
}


for(i=1;i<=Grid_Colums;i++){
for(j=1;j<=Grid_Rows;j++){
if(j==1){
}
else if(i==1 && j!=1 && j!=Grid_Rows){
///do nothing
}
else if(j==Grid_Rows){
//do nothing
}
else if(i==Grid_Colums && j!=1 && j!=Grid_Rows){
//do nothing
}
///the avarege of all the spaces around the  the current space using (a+b+c+d+e+f+g+h+i)/9= average
else{Log[i][j]=(((Log[1-i][1-j])+(Log[1-i][j])+(Log[1-i][1+j])+(Log[i][1-j])+(Log[i][j])+(Log[i][1+j])+(Log[1+i][1-j])+(Log[1+i][j])+(Log[1+i][1+j]))/9);
}
}
}
///prints grid 
for(i=1;i<=Grid_Colums;i++){
for(j=1;j<=Grid_Rows;j++){
printf("%8.2lf",Log[i][j],i,j);
}
}

printf("\n");



return 0;
}

here is an example of the out put

Enter the top side temp:34
Enter the right side temp:45
Enter the bottom side temp:56
Enter the left side temp:2
How many rows in the grid?10
How many columns in the grid?10
