ead it and find any grammar or other mistakes? Can you also tell please that if this essay fits the criteria for being an argumentative essay and if it is a good argumentative essay? It is a 350 word essay and I can't cross the limit more. Every relationship has its own importance. Marriage is a relationship, based on love or compromise, in which male and female interact and spend their life together. According to research, love and arranged marriage go hand-in-hand. Both are on the average scale because marriage has simply become part of business; however in modern era, the ratio of love marriage is increasing. Love marriages are considered superior because of understanding that both persons have for each other before marrying. In love marriage, couples have mutual understanding. Despite facing numerous problems such as convincing parents to accept their choices and warding off false accusations and comments; however, these challenges guide them to happy life. In arranged marriages, both partners are unknown to each other and start their lives according to their parents' guidance. These couples don't make their own choices, but accept their parent’s demands. This leads to apathy for needs and feelings of their partner, which leads to weak bond between them. In love marriages, couples always demonstrate respect to their partner's family members. They make many compromises to not hurt their partners; however, they still are able to speak frankly and openly. In arranged marriages, partners tend to speak with hesitation and tend to consider their own needs before those of their partner or partner's family. In married life, couples should know what their partner prefer. This can only happen if the couple knows each other well before marrying. In arranged marriages, partners feel hesitation to share their feelings, likes, and dislikes; however, in love marriage partners already have an understanding of their partner's needs and just need to respect them and create a bond with their partner's family members. They care for each other's feelings and respect their boundaries. In conclusion, arranged marriages are guided by parents whereas love marriages allow a couple the freedom to assess the future complexities that may arise in their lives. Love marriages contain mutual understanding that allows couples to solve their issues practically rather than emotionally. In a successful relationship, considering other person's feelings is a priority, which is commonly found in love marriages.

rst-year students at her small college. Participants in the study (first-year students at her college) complete an online memory task. The students are first shown a list of 120 words. Next, they are shown a list that includes five new words that are completely unrelated to words on the original list. Then they are asked to identify the words on the second list that appeared on the original list. She uses the percentage of new unrelated words that were mistakenly thought to be on the original list as her measure of memory quality. She also asks the students to report several characteristics such as their age, their gender, and a self-assessment of their study skills. Each of the 500 first-year students (268 males and 232 females) at her school volunteers to participate. The professor chose 50 students at random to complete the memory task and answer the questions. The average percentage of new unrelated words that were mistakenly thought to be on the original list was 12%. The professor infers that if all 500 first-year students had completed the study, the results would show that an average of 12% (plus or minus sampling error) of new words were mistakenly identified as original words despite being completely unrelated to the words on the original list.

onal array. Marks of each students : CSE115 CSE 173 CSE215 Jamal 80 70 60 Mamunul 57 76 74 Saad 67 98 87 Rana 98 87 90 Mabubur 45 97 34 1. How to create function named myTotalMark which calculate Total Obtained marks of each students, Print Total marks of each students with their name. Note: Create 2D array using marks in this function and pass same array to next function(specificStudent and specificMarks) as a parameter.So you have to call those function from myTotalMark. 2. Now create another function named specificMarks which calculate Total average marks of Three specific subjects according to teachers input(1 to 5).If teacher Enter 1 it will calculate average marks of CSE115 course.Store marks in a Array and print average marks with subject name. void specificMarks(int subject[5][3]) 3. Create another function named specificStudent which calculate Three Specific students marks according to teachers input(1 to 10).If teacher Enter 1 it will calculate the total marks of Jamal.Store marks in a Array and print three students mark with their name.Pass this array to Grade function as a parameter. void specificStudent (int student[5][3]) 4. Create another funciton named grade which Calculate grade of Three students which were obtained in specificStudent Function.Using this range: void grade(int number[ ] ) 100-200 B+ 201-300 A- 301-500 A 5. Now create main function and call only myTotalMark function to display output. please do it in #c program
