how do you do 7?

c language please

6. Create a script with if, else if, and else conditionals to calculate the Total Resistance (R_T) 1) r1 r2, and r3 are connected in series manner. (R_Tur1+r2r3) 2) ri, r2, and r3 are connected in parallel manner.(R_T = 1/((1/1)-(1/2) (1/r3)) ) 3) r1 is connected to the parallelly connected r2 and r3 in series manner. (Let's call this Combination) (R_T=112xr3/(12+13)) The output should be What is the resistance of R1? [You type in the value] What is the resistance of R2? [You type in the value] What is the resistance of R3? [You type in the value] What kind of combination result are you looking for? [You type in S, P, or C) The Total Resistance is your result ohms sinceri, 12.r3 are connected in series, parallel combination) manner. Test the result with ri - 100,12 - 200, and r3 - 300 7. Repeat problem 6. This time use "switch". Do some reading on issues with scanf() when we have multiple user input Grading: Problems 1 and 3 (2 points - 1.50 Actual Scripts 0.5 Pseudo Codes) Try to make Pseudo Code as detailed as possible Problems 4,5,6,7 (1 Points Each Scripts)
