I am doing a project regarding OFDM.I used 64 QAM to modulate the data . The
output of QAM is complex.
Can the complex output be given directly to perform IFFT ?
can the output of QAM be given directly to IFFT ?

If this is transmission side, then yes. Be careful to choose iFFT size depending on
number of subchannels. Here is a good description (sorry not MATLAB):
