}
compiler dose not read this minimum function
float minimum() {
if(a[1]<a[2]&&a[1]<a[3])
printf("station 1 is the nearest");
else if(a[2]<a[3]&&a[2]<a[1])
printf("station 2 is the nearest");
else if(a[3]<a[1]&&a[3]<a[2])
printf("station 2 is the nearest");
}
}
compiler dose not detect minimum function how to solve it
when it compile it shows an error message impilicit decleration of function minimum
void main() {
cordianation_entry();
results_analysis();
minimum();
}
CodePudding user response:
The problem is you did not use {}
parenthesis correctly. In particular this function:
float results_analysis() {
for(i=1;i<4;i ) {
a[i] = (pow((val[i][0]-val[0][0]),2)) (pow((val[i][1]-val[0][1]),2));
a[i]=sqrt(a[i]);
printf("\n*distance to station %d is %f\n",i,a[i]);
if(a[i]<100)
printf("\tDistance is Low");
else if(a[i]<1000 && a[i]>=100)
printf("\tDistance is Moderate");
else
printf("\tDistance is High");
}
} // <--- Missing in your code
and there is a }
parenthesis that is not supposed to be there:
float minimum() {
if(a[1]<a[2]&&a[1]<a[3])
printf("station 1 is the nearest");
else if(a[2]<a[3]&&a[2]<a[1])
printf("station 2 is the nearest");
else if(a[3]<a[1]&&a[3]<a[2])
printf("station 2 is the nearest");
}
// } <--- Wrong
