why when i am running the program and entering the special characters, the program is not accepting them.

// Online C compiler to run C program online
#include <stdio.h>



void sum(int x,int y)
{
int add=x+y;
printf("%d",add);
}
void subtract(int x,int y)
{
int sub=x-y;
printf("%d",sub);
}
void product(int x,int y)
{
int pro=x*y;
printf("%d",pro);
}
void division(int x,int y)
{
int div=x/y;
printf("%d",div);
}
int main() {
int x,y;
char c;
printf("type 2 num\n");
scanf("%d%d",&x,&y);

Leave a space before scanf char, Try this -

scanf(" %c", &c);

Here -

#include <stdio.h>

void sum(int x, int y)
{
    int add = x+y;
    printf("%d", add);
}

void subtract(int x, int y)
{
    int sub = x-y;
    printf("%d", sub);
}

void product(int x, int y)
{
    int pro = x*y;
    printf("%d", pro);
}

void division(int x, int y)
{
    int div = x/y;
    printf("%d", div);
}

int main()
{
    int x, y;
    char c;
    printf("type 2 num\n");
    scanf("%d%d", &x, &y);
    printf("press + for sum, - for sub, * for prod, / for div\n");
    scanf(" %c", &c);
    switch (c)
    {
        case '+':
            sum(x,y);
        break;
        case '-':
            subtract(x,y);
        break;
        case '*':
            product(x,y);
        break;
        case '/':
            division(x,y);
        break;
        default:
            printf("NONE");
        break;
    }

    return 0;
}
