我对编码很新,并且已经构建了一个代码来插入一个三次样条曲线,但是我坚持使用最后一个等式执行以下错误:_"无效操作数到二进制^(有'double'和'double')| "
问题出在代码的最后一位,两个第一行的"population =".如果有人能指出我正确的方向,我真的很感激.
#include <stdio.h>
main () {
int x;
int y;
double stats[10][2];
double gpp[8][9] = {0};
double gppr[10] = {0};
double year;
double population;
int xi = 0;
year=1950;
population=0;
x=0;
stats[0][0] = 1930; stats[1][0] = 1940; stats[2][0] = 1949;
stats[3][0] = 1955; stats[4][0] = 1960; stats[5][0] = 1970;
stats[6][0] = 1980; stats[7][0] = 1990; stats[8][0] = 2000;
stats[9][0] = 2005;
stats[0][1] = 21.058; stats[1][1] = 23.547; stats[2][1] = 20.167;
