I haven't find any mistake in the following code, indeed I can't get :p
It doesn't show the correct answer. Please check the code and tell me where the logic is incorrect.Please help! I am trying it from last night

Code:: #include #include #include int main(void){ int n=3,i,j,key; double sum,x0[3],x[3]; double a[3][3]={2,1,1, 3,5,2, 2,1,4}; double b[3]={5,15,8}; printf("Starting...\n"); for(i=0;i x0[i]=b[i]/a[i][i]; key=0; while(key==0){ for(i=0;i { sum=b[i]; for(j=0;j if(i!=j) sum=sum-(a[i][j]*x0[j]); } x[i]=sum/a[i][i]; if(key==0){ if(fabs((x[i]-x[0]))>0.00000001) key=1; } } if(key==1){ x0[i]=x[i]; } } for(i=0;i printf("%f\n\n", x[i]); printf("END!"); getch(); return 0; }
