用二分法求方程式X3-X-1=0在区间【1,1.5】内的近似解 这题如何解啊

#include #include #include #define EPS 1e-6#define DELTA 1e-6int main(){float x;float a,b;float f(float);float Bisection(float,float,float(*f)(float));a=1;b=1。5;x=Bisection(a,b,f);system("pause");return 0;}//float Bisection( float a,float b,float (*f)(float) ){float c,fc,fa=f(a),fb=f(b);int n=1;cout
