2 C Errors Incompatible type and expected type -
this question has answer here:
- passing matrix function, c 5 answers
i'm trying store 3 sets of 5 double numbers user input. need store information in 3 x 5 array , compute average of each set of 5 values.
i can't figure out how fix 2 errors.
first error: hw9.c:27:2 error: incompatible type argument 1 of 'set_average' set_average (array[row][col]); ^
second error: hw9.c:8:6: note: expected 'double (*)[5]' argument of type 'double' void set_average(double array[row][col]);
thanks , suggestions.
#include <stdio.h> #define row 3 #define col 5 void set_average(double array[row][col]); void all_average(double array[row][col]); void find_largest(double array[row][col]); int main(void) { double array[row][col]; int i, j; printf("enter 3 sets of 5 double numbers.\n"); (i = 0; < 3; i++) (j = 0; j < 5; j++) { printf("enter elements until done.\n"); printf("enter %d%d: ",i+1,j+1); scanf("%le", &array[i][j]); } printf("done entering numbers.\n"); printf("now it's time compute average of each set of 5 values\n"); set_average (array[row][col]); return 0; } void set_average(double array[row][col]) { int r; //row int c; double sum; double avg; //average (r = 0; r < row; r++) (c = 0; c < col; c++) { sum += array[r][c]; } avg = sum / 5; printf("the average %le\n", avg); }
you calling function as
set_average (array[row][col]); instead of
set_average (array); function defined void set_average(double array[row][col]) expects array of row. each has array of col items doubles. error reported because function called 1 double argument.
