Hello sanaulla,
COMPUTER SCIENCE ENGINEERING AND ELECTRONICS AND COMMUNICATION ENGINEERING are literally two different branches. So, does their scope vary accordingly.
Let me clarify the actual difference. See, the difference in both of these branches are the subjects. In CSE, it is related to computer science, data structure, algorithm, OOPS, DBMS and many more subjects which are very important for placement and career as from CSE an individual can apply for software engineer roles, developer roles, analyst and many more.
Coming to ECE, it is a semi core branch although the placements are also good you need to work extremely hard in this branch as it is difficult than the CSE. The subjects in each mainly focus on electronics and electrical having circuits, graphs, complex questions etc. The placement is good if you are from TIER1/2 colleges because they provide exposure to their students along with academics and curriculum. If you are from TIER 3 colleges then you need to work harder for the placements.
But the choice is yours. So, choose accordingly.
