What is required in each C program?

The program must have at least one function.

The program does not require any function.

Input data

Output data

If ((a > b) && (a <= c))

a = a + 1;

else

c = c+1;

A = 11, c = 10

A = 10, c = 10

A = 10, c = 11

A = 11, c = 11

int num = 58;

num % = 11;

b = s + b

s = b - s

b = b - s

Exchange the values of s and b

Transfer the values of s and b

Add or subtract the values of s and b

Transfer the values of b and s
