conditional jump or move

What does conditional jump or move depends on uninitialized value mean?
The error message "Conditional jump or move depends on uninitialized value(s)" essentially means Valgrind has determined that the result of your program depends on uninitialized memory.
Sometimes you will also see the message "Use of uninitialized value of size N".
In C,C++ uninitialized variable variables contains garbage value but static variables contains default value that is 0,and global variables also initialized with default value 0.
Note global variables are those variables which are declared outside the main function.

What is a conditional jump in C?

A conditional jump is an instruction that changes the value of the instruction pointer (IP) register, which holds the address of the next instruction to execute, based on the result of a previous comparison or arithmetic operation.
