Populate int array with a char array full of numbers in C (char array to int array)

My Char array allows for a user to input a purely numeric string, thus storing each digit in its own array space. I need to assign each element of the char array to the corresponding location in the int array. How do i store the actual numeral rather than the the ASCII equivalent

ex. if I enter 9 as the string, i don't want 57 (the ASCII value) 开发者_Go百科but the numeral 9.

int main()   
{

    int x[256] = {0};
    int y[256] = {0};

    char temp1[256] = {0};
    char temp2[256] = {0};

    char sum[256] = {0};
    printf("Please enter a number: ");
    scanf("%s", &temp1); 

    printf("Please enter second number: ");
    scanf("%s", &temp2);

    for(i=0; i<256; i++)
    {
        x[i] = ((int)temp1[i]);
        y[i] = ((int)temp2[i]);         
    }

Change:

    x[i] = ((int)temp1[i]);
    y[i] = ((int)temp2[i]);         

to:

    x[i] = temp1[i] - '0';
    y[i] = temp2[i] - '0';         

Note that you also need to fix your scanf calls - change:

printf("Please enter a number: ");
scanf("%s", &temp1); 

printf("Please enter second number: ");
scanf("%s", &temp2);

to:

printf("Please enter a number: ");
scanf("%s", temp1); 

printf("Please enter second number: ");
scanf("%s", temp2);

int main(void) {
int x = 0;
int y = 0 
char input[12] = {0}; --->initialize var input 


scanf("%s", &input[0]);
int ch_len = strlen(input)/sizeof(char); --create length of input[] array
int digit[ch_len];    --->initialize digit which size is how many character in input[] array
fflush(stdin);

while (input[y] != '\0') {
if (isdigit(input[y])) {
    digit[x++] = input[y++]-'0';
    count++;
}
else y++;
}
}
