C

========== 1. Learning_C/learning_c.c

My learning philosophy:

1. Practice the syntax of the new language and test my understanding of it by putting it into various situations;
2. Integrate what I have leant with the new piece I'm learning to improve my understanding and view of the new language;
3. Compare with other languages I have learnt and try to solve some similar problems encountered before with the new language.

My goals:

1. Be familiar with and master the new language;
2. Through writing codes and testing of them, take good notes of the new language;
3. Form my own syntax library of the new language for future review.

========== 4. Combine_FAC_RM_454/{*}

This code is the core part of adding FAC by RM to get the final photoionization cross section. The other codes are in Bash/Combine_FAC_RM_454.

========== 5. Generate_FAC_Mesh_454/{*}

Along with other codes in Generate_FAC_Mesh_454/ in repositories Bash & Python, this program is used to generate the FAC energy mesh for 454 levels.
