Question

hi i have this function

int printofarray(int *j,double *n)
{
int x,k;
k=*j;
if(n==NULL) {
printf("array was not created\n");
return 1;}

for(x=0;x<k;x++){
printf("%.2lf\n",*(n+x));}

return 0;

410.70

but i want to write them this way

  34.77
6114.05
 410.70

%lf specifies to read a double, but you’re trying to store the result in a float, which is half the size. The specifier for a float is just %f — or use a double; floats are fairly useless on modern general-purpose computers.
