2. Create a C program that contains a printf to take as parameter a string and a list of arguments of variables. The string must contain only the forrkat identifiers for characters %e, double %d, float %f, and string %s specifiers and characters. The function is to process the string and the list of arguments and to call of printf() to output their values. The program is to display the following result: k=5+1.2 = 6.2 (plus the Os). 3. Write C code on how you feel at the moment by using only both a character and an inte ger data type. 4. Write a C program that declares two floating-point variables (1. j), assign to them two positive values (3.45 and 6.78), swaps their integer parts such that I becomes 6.45 and j becomes 3.78 respectively
