c - Passing array into function not giving correct answer -

this question has answer here:

i wrote function :

string par(int a[]){ int s=sizeof(a)/sizeof(*a); cout<<s<<endl; /*     ..do */

}

the main function written as:

nt main(){  int a[]={1,5,11,5};  cout<<sizeof(a)/sizeof(*a)<<endl;  cout<<par(a)<<endl;

}

the output is:

4

1

while believe should same passed same array. kindly point out mistake..thanks..

in c++ when pass array argument function, you're passing pointer array.

since size of pointer , int 4 or 8 (depending on abi, , since you're getting 1 guess have 32-bit machine) you're getting 4/4 1.

int s=sizeof(a)/sizeof(*a); 1.

you should pass size argument instead of trying calculate inside function:

string par(int a[], int size)
