int a, b, rval;

printf(" Enter two integers: "); rval = scanf("%d%d", &a, &b);

Problem 1 - Short answer (Please explain through) a. What decimal (base 10) values are stored in the variables x and y when the user enters the following? 1.23 4 float x; (there is one space between each of the group of numbers) int y scanf("%d%f", &y, &x); b. What decimal values are stored in the variables x, y, and letter when the user enters the following? 77 a 19 int x, y; (there is one space between each of the input groups) char letter; scanf("%d %5%d", &X, &letter, &y); c. What will be the output of the following program? #include int main() Program Output unsigned char i 102, j -21, k-10; printf("result: %d ", 5/10); printf("%c %d ", ++i, j % k ); return 0; d. Write a printf statement that prints the value stored in the variable balance. The field width of balance must be a total of 10 with 2 places to the right of the decimal point. Assume the variable has been declared as follows: double balance; What values does the following scanf statement return upon failure and return upon success? e
