Problem solving through Programming In C - Session I - Program II Change of score

Those who have answered the program -II of Session-I correctly regardless of whichever printf statement ("Total Repeated elements" or "Total repeated elements" ) you have used may notice that their score is shown as 50% (for this particular program only).  You do not need to worry about it. It will be treated as full marks (100%) while calculating the final score.  This is mainly done to incorporate both the printf statement.  Thanks

Some Corrections in Video lectures of Week-1 - Problem Solving through Programming in C

Dear Learners, At 11.25 mins of the Lecture 3: Flow Chart and Pseudocode , in the flow chart of printing average of 3 numbers the final print statement should be “ Print AVG ” instead of “ Print SUM ” as we are finding the Average of 3 numbers. At 7.12 mins of the Lecture 3: Flow Chart and Pseudocode , Regarding the symbols used to represent the flow chart, generally oblong symbol is used to represent START and END of a flow chart and a parallelogram symbol is used to represent INPUT and OUTPUT, and the Circle symbol is used as a connector, when we need to represent the continuation of flow chart when there is shortage of space.  At 18.52 mins of the Lecture 3: Flow Chart and Pseudocode , in the flow chart of printing the average of N numbers: after reading the number and storing it in N we should store in another variable say M. So after the statement “ Read the value of N ” there will be another statement which will be “ M=N ” in a rectangular box. And after the decision box instead of AVG=SUM/N it will be AVG=SUM/M , as the value of N is becoming zero at the end of the decision loop.  At 28.07mins of the Lecture 3: Flow Chart and Pseudocode : in the flow chart for finding Max of N positive integer please follow the flow chart drawn in blue colour. Please ignore the corrections made. -NPTEL Team
