This program demonstrates the use of basic C data types to store and display values. C supports integer and real data types such as int and float. The char type is used to store character values and is treated as an integral type.

#include <stdio.h>

int main()
{
    int account_number;
    float amount;
    char currency;

    account_number = 1024;
    amount = 100.5;
    currency = '$';

    printf("Mr. Cat with account number %d owes me %f %c\n", account_number, amount, currency);
    return 0;
}

Output:
Mr. Cat with account number 1024 owes me 100.500000 $

int is used to store whole numbers.
float is used to store decimal values (single precision).
char stores a single character and is internally represented as an integer value.

printf() uses format specifiers to print values:

• %d → integer
• %f → float
• %c → character
