Storing and Iterating through user inputs in C - c

Question

The program below asks the user to input 10 integer numbers and stores the user inputs in a corresponding array of 10 ints. When an input is done it should iterate through the already existing user inputs and print them out. I want to iterate through the stored values in storedinputs by using a function like strlen(), however the stored values are not strings but are integers. How could i do such a thing.
int main(void) {
int storedinputs[10] = {0};
int input;
for(int i = 0; i < 10; i++) {
printf("\nPlayer input:");
scanf("%d", &input);
storedinputs[i] = input;
for(int s = 0; s < strlen(storedinputs); s++) {
printf("Inputs %d", storedinputs);
}
}
return 0;
}
Expected Output:
Player input: 1
Inputs: 1
Player input: 3
Inputs: 1 3
Player input: 60
Inputs: 1 3 60

Answer 1

You cannot use the function strlen() because storedinputs is an array of integers. If you want to print the stored values every time you insert a new one you should edit the for loop condition, as suggested by Weather Vane in the comments, as follows:
for(int s = 0; s <= i; s++)
The variable i indicates the number of the cell containing the last number added.

Answer 2

Here is the fixed code including error checking.
Superfluous input needs to be skipped over (while(fgetc(stdin) != '\n');)
scanf has insufficient error checking capabilities. Use combination of fgets and strtol.
In the internal loop you need to terminate when outer loop counter is reached
You should not count invalid input (Therefore, I replaced outer for loop by a while loop)
You should not store invalid inputs in your array
You need to index your stored inputs when printing them out

#include <stdlib.h>
#include <stdio.h>
#include <limits.h>
#include <errno.h>
#include <string.h>
// In contrast to #define this provides a nice means for grouping constants
// and it can be changed into a typedef, later on
// Furthermore, it's a compiler aware constant
enum {INPUT_COUNT = 10, MAX_INPUT_LENGTH = 20};
int main(void) {
int input_count = 0; // The count of valid inputs
char input[MAX_INPUT_LENGTH + 1] = {0}; // The string buf for one input
int converted_input; // Result of integer conversion
int storedinputs[INPUT_COUNT] = {0}; // Array with valid results
char *endptr; // Needed for strtol error checking
while(input_count < 10) { // Loop over 10 valid inputs
printf("\nPlayer input (Enter single integer value):");
fgets(input, sizeof(input), stdin);
printf("Got input: %s\n", input); // input contains '\n', already
// If input was longer than MAX_INPUT_LENGTH, get rid of remains
if (input[strlen(input) - 1] != '\n') {
while(fgetc(stdin) != '\n');
}
// Reset errno, so strtol returns a fresh value
errno = 0;
converted_input = strtol(input, &endptr, 10);
// The errno is set if input is out of range
if (errno) {
perror("Conversion error");
continue;
}
// Here we have invalid characters present in the input
if ( (endptr == input) || (*endptr != '\n') ) {
printf("Please enter single integer!\n");
continue;
}
// Everything fine, so we can store result
storedinputs[input_count] = converted_input;
// Now we output all valid inputs, up to now
printf("Inputs: ");
for(int s = 0; s <= input_count; s++) {
printf("%d ", storedinputs[s]);
}
printf("\n");
++input_count;
}
return 0;
}
Output:
Player input (Enter single integer value):12
Got input: 12
Inputs: 12
Player input (Enter single integer value):13
Got input: 13
Inputs: 12 13
Player input (Enter single integer value):14
Got input: 14
Inputs: 12 13 14
Player input (Enter single integer value):1324567543245678654324567

OK, 10 inputs have been made
