Bonjour à tous, 
 
je ne comprend pas l'origine de la "segmentation fault" qui m'est envoyé lorsque j'essaye de compiler le programme ci dessous quelqu'un pourrait il m'éclairer? : 
 
#include <stdio.h> 
#include <math.h> 
 
 
 
double partition (double, double, double); 
double expo (double, double, double,double); 
 
int main() 
 
{ 
int i,j; 
double t[4],t1[4],P[4]; 
double z2=0.0,Kb=1.0,T=1.0; 
FILE *f_in1,*f_in2,*f_out1; 
FILE *f_in, *f_out; 
 
/*printf("dimensions de la matrice?"); 
scanf("%i",&N1);*/ 
 
f_in=fopen("ei.txt","r"); 
 
fscanf(f_in,"%f", &t[i]); 
 
for (i=0; i<=(4); i++) 
 
{ 
z2=(z2+partition (t[i],Kb,T)); 
} 
 
f_in2=fopen("ei.txt","r"); 
f_out1=fopen("proba_ei.txt","w"); 
 
fscanf(f_in2,"%f",&t1[j]); 
 
for (j=0;j<=(4);j++) 
{ 
P[j]=((exp(-t1[j]/(Kb*T)))/z2); 
} 
 
fprintf(f_out1,"%f",&P[j]); 
} 
 
double partition (double x, double y, double z) 
 
{ 
double z1; 
 
{ 
z1=(z1+(exp(x/(y*z)))); 
} 
 
return z1; 
 
} 
 
double expo (double x, double y, double z,double k) 
{ 
double z3; 
 
 
 
z3=((exp(x/(y*z)))/k); 
}
