hi;

i did a function that get inputs of equation from user but i want to get from file

let file :Code:void getInput( int numUnKnowns, double** mat ){ int i, j; printf ( "\nEnter values for the specified row and column below ...\n" "(The last column is the value for the RHS of the equation.)\n" ); for( i = 0 ; i < numUnKnowns ; i++ ) { mat[i] = (double*) malloc( (numUnKnowns+1)*sizeof(double) ); puts(""); for( j = 0 ; j < numUnKnowns+1 ; j++ ) { printf("matrix[%d][%d] : ", i, j); if( scanf("%lf", &mat[i][j]) != 1 ) { --j; puts("Bad entry ... try again with a 'real' number."); } while( getchar() != '\n' ) ; /* flush stdin ... */ } } printf("\nThe matrix entered:\n\n"); for( i = 0 ; i < numUnKnowns ; i++ ) { for( j = 0 ; j < numUnKnowns+1 ; j++ ) printf("%+9f ", mat[i][j]); puts(""); } printf("\nPress 'Enter' to start iteration ... "); getchar(); }

7a - 2b + c + 2d = 3

2a + 8b + 3c + d = -2

-a + 5c + 2d = 5

2b - c + 4d = 4

can any one help me how function read from file.

thanks
