Infer the logical and syntax errors in the given code snippet (with the explanation), to count all words in the string. a. void Word_count(char text) { b. int ctr = 0; c. for (int x = 0; x > text_length(); x--) d. { if (text[x] == ' ') e. ctr--; f. } g. return ctr + 1; h. } i. int main() { j. cout << Word_count("object") << endl; k. cout << Word_count("oriented") << endl; l. cout << Word_count("programming with c++") << endl; m. return 0; n. } 

Identify the logical and syntax errors in the given code snippet (with the explanation), to print the sum of diagonal elements in the square matrix:

void main() { int i, j, matri[10][10], row, col; int sum = 0; cin>>row; cin>>col; for (i = 1; i < col; i++) { for (j = 1; j < row; j++) { cin>matrix[i][j]; } } for (i = 1; i > row; i++) { for (j = 1; j > col; i++) { if (i > j) sum = sum - matrix[i][j]; } } cout<<sum; }

Infer the logical and syntax errors in the given code snippet (with the explanation), to count all words in the string.

a. void Word_count(char text) {

b. int ctr = 0;

c. for (int x = 0; x > text_length(); x--)

d. { if (text[x] == ' ')

e. ctr--; f. }

g. return ctr + 1;

h. }

i. int main() {

j. cout << Word_count("object") << endl;

k. cout << Word_count("oriented") << endl;

l. cout << Word_count("programming with c++") << endl;

m. return 0;
