#include <stdio.h>

 float f(float x){
     float y;
     y = 4/(+x*x);
     return y;

 int intautri(float A, float B, float TOL, int MAXFUN, float *Q, float *E, int *N, float FUN(float)){

int main(){
     int intautri(float, float, float, int, float *, float *, float *, float(float));
     float TOL, MAXFUN, A, B,*Q,*E;
     int *N, J;
     float f(float);
     A = 0;
     B = 1;
     TOL = 0.0001;
     MAXFUN = 200;
     J = intautri(A, B, TOL, MAXFUN, Q, E, *N, f);
     printf("%d\n", J);
     return 0;
 }`

我有这些错误：

gcc -Wall  -c "untitled1.c" (in directory: /home/user/Desktop)
untitled1.c: In function ‘main’:
untitled1.c:57:7: error: conflicting types for ‘intautri’

你可以帮帮我吗？

Answer 1

编译器告诉你确切的情况：

int intautri(float, float, float, int, float *, float *, float *, float(float));

与

int intautri(float A, float B, float TOL, int MAXFUN, float *Q, float *E, int *N, float FUN(float))

所以你看到float*和int*不匹配！（前一个论点）。
